Shuleykin in 1922. During 1926-27, Vvedenskiy and others investigated the possibility of ' at practical application of the attenuation or gain effects ptduced metric wavelengths by metallic dnd other objects. These investigations showed that-the electric field is inversely proportional to the square of the distance from the transmitting antennae and directly proportional to the height of the transmitting and receiving antennae. In 1931, Shein and Kuzovkin designed transmitters and receivers capable of operating at distances up to 20 km, while, in 1932-33, a regular communication link at metre waves was established between Moscow and hoginsk (a distance of 45 km). The experiments carried out by means of that system showed that Card 1/4 109-11-4/8 Investigations of the Tropospheric Propagation of Metre, Decimetre and Centimetre Radio-waves in the USSR: short waves could bepropagated beyond the standard radio horizon.~ The-problem of the propagation beyond the line-of- sight was investigated in 1933 by a special expedition, which measured the fields over the Black Bea at a wavelength of 60 cm, and at distances up to 100 km. During 1936-37, Vvedinskiy propbsed & method for determining the affect of the height of the antennae and the electrical parameters of the soil on the diffraction of the shortwaves. The problem of the equivalent Earth's radius was dealt with by V.A. Tok who, in 1946 proposed an original and general treatment of the diffraction P~enomena. During 194?-48, & number of experimental investigations of the radio-wave propagation on wavelengths ranging from 8 m to 3 cm were oarried out over the Baltic, which showed that the Yok theory was in good agreement with the experimental results. Xhiring the 19401s~ the propagation of ultra-shortwaves was studied over distances much longer than those which dan be -anounted tor by the diffraotion-refraotion the6ki~Cli These effects can be explained by the theory of the atko 9% heric ducts or waveguides.

Thus,,in.1946, Braude'and Ostrovskiy evaluated the fields over e ea and dry land for wavelengths of 0.3 to 9 mI while A.N. Shchukin and others took into aceomat the effect of the tropospheric irregulrities. Durirg 1952-55, A.I. Kalinin derived formulae for the calcul- ation of the fields at short distances and at distances well beyond the line-of-sight; he also'determined the limits of applicability of the optical diffraction theory. In 1952 M.A. Leontovich, G.A. Grinberg and others made a theoretical investigation of the influence of the Earth-surface irregulwities on the wave propagation. The problem of the influence of the meteorological conditions on the wave propagation was 3tudied by V.H.

PERIODICAL: Radiotekhnika, 1957, Vol 12, Nr 1, pp 3-11 (U.S.R.R.) Received: 2 / 1957 Reviewed: 3 / 1957 ABSTRACT: In the introduction the possibility of radiotranamission within the range of ultrachort waves over distances hitherto considered to be impossible is pointed out. A short survey of the development of ultrashort wave technics from the twenties up to the present day in given. Only such phenomena are dealt with as are due to the troposphere and not to the ionosphere. The terminology is disoussed, the various expressions used are mentionedo and it is said that the term "tropospheric long-distance propagation of ultrashort waves", which was ueed by-the authorsp.is the nearest approach to reality. There follows a survej of systematic research work carried out in this field in the USA9 after which some experimental data are dealt with. It was pointed out that it has booome a tradition since 1950 to assume a dependence for the field in powers of distance, but that this has as yet by no means been proved.to be true. The methods de- veloped by NORTHON, REICE and VOGLER and their "prediction curve" are disoussed in detail. The corresponding diagrams are shown and it is said that the authors -of this method obtained their formulae by means of a method which, though very complicated, is by no means convincing. On the other hand it cannot be denied that this method offers the possibility of covering an abundance of experimental material by means of an acceptable empirical formula, and that this curve is CARD 1 / 2 PA - 2011 The Tropospheric Long-D19tanoe Propagation of Ultrashort Waves. preferable to all other curves and nomograms hitherto -published and suggested. Next, transition of the diffraction zont into the troposphere and the eXptTi- ments ea:.rrie& out in this.connection by Trol4se are dealt with. It is found that modern diffraction theories are rather clumsy In those cases in which the Influence exercised by the relief of the earth surface cannot be computed. It is also aifficult to draw limits between zones according to the character of dying down. The curves recorded from an airplane by AMES9 NEVIMAN, and ROGERS are shown and the mathematical solutions found by NORTON.. VOGLER, NUNSFIELD and SHORT are mentioned. In conclusion the authors state that by means of ex- perimenta it is as yet not possible to supply a clear answer to the question as to whother a certain field is "totally scattered" or not.

A survey is given of the development of the theory according to which the dispersion by the in- hcnogencous parts of the ionosphere is a possible factor for the prop- agation of radio waves. BOOKER. and GORDCH, VILLARS and WELSSUFF, aj well an NORTM, RICE and VOGLER are referred to. The latter three applied the theory developed by VILLARS and WEISSKOFF for the iono- sphere in 1954 to the troposphere. Of the two processes suggested by them they give preference to the one in which the turbulent current vortex is considered as being in a field with the gradients of the di- eleotr1o transparencor. Also this theory still needs further essential elaboration. Next, coherent dispersion, refraction, and diffraction are dealt with. The theories of BW and XWY (1955), of J-FZ3NSTE3N, CARROLL and NORTHOVER are discussed. It is shown that the-points of aiscus3ion are not yet settled, that the dispersion theories are due to the fading in the relays, and the factors connected herewith, that the theories of CARROLL and NORTHOVEEL can not explain these phenomena, card 1/2 PA - 2292 The Remote Propagation of Ultrashort Waves In the Troposphere. that also the opponents of those theoriest who consider the theory of the incoherent diapersion as the only correct onot are wrong# sinoo &1s0 theaft MxtarLfta can UrA ftx~l~'L'ft twatut.

No uniform value of 2 (A) has been found as yet9 probably because of the changeability oi the tropospheric structure and mezeorological conditions; 3) Signal and time: Signal fading may be rapid or slow. bloat Informa- tion concerns 300 - 500 km traces. Slow fading is caused by the appear8mee or disappearance of inversioh layerep large irregulari- ties and changes in the value of de/dh. Usually the signal Btrength is greater in the evening and at nightf clearer in summer than in winter and at shorter (100-150 km) rather than longer (400 - 500 km) distances. The amplitude is related to frequency; also, as it combines with slow fadingg the average amount of fading increases reaching, according to some sources, a maximum at 100-130 km. Others maintain that it declines with increase in distance to an equal emmyner ana winter value of 3 .. 10 db at 900 kmi 4) Loss of antennse amplification: The phenomenon occurs beyond the horizon and meEais that for an antenna with an amplification coefficient G, exceeding 35-40 dbf amplification io less than in free space. To account for this there are two hypotheses: (1) Spreading of radio- Card 2/8 24460 A survey of work on the ... S/109/61/006/006/'001/016 D204/D303 waves In a statistically non-homogeneous medium leads to distor- tion of the wave front in the plane of the receiving antenna and thus the energy absorbed is less than in the absence of amplitude and phase fluctuation, (2) elementary waves with various random angles of approach may reach the receiving antenna. These hypothe- ses have been investigated but comparison of results is hampered by differences in experimental conditions. For a 300 km trace the amplification loss Increases with increase in the average amplifi- cation of receiving and transmitting antennae and with an increase of D to 300 - 500 km and f = 2290 megacycles. At greater distances the lone falls; 5) Signal distortion: Work in this field either treats the tropoophere as an ideal quadruple network or aims to determ.~ne the amplitude correlation of the signal components on differont frequencies in the transmitted spectrum. If with anten- nae wi*,h low directivity the amplitude of aelayed waves is dimi- nl,i~hed by diffraction weakening of the earth's surface and the "directivity" of the -troposphere, then at antennae with narrow patterns the amplitude of these waves decreases because of the di- Card 3/8 24460 C;/109/61/006/006/001/016 I', A survey of work on the ... D204ID303 rectivity of the antenna. The maximum transmitted frequency band depends on the width of the directivity pattern of the antenna. The random nature of the tropospheric radiation means that signal dis- tortiori. has a random pattern as experiments in the USSR have con- firmed. Two separated antennae in space diminish distortion and guarantee a large carrying capacity of tropospheric radio links; 6) Radio-meteorological researchi Refractometric measurements have dealt with the structure of the troposphere and, in particular, the value of 4(h)9 (Z~E)2 and the area of turbulence )2 usually varies within the range 0.3 - 3N units and irregular layers are usually 1 - 300 m thick. "Jump" intensity in these rs~gions is usually 2 - 50 or 60 N uniteg large especially in the "invisible U clouds". It was stated that at a height h = 3000 m and more (6 E)2/,, is too small to explain distant fields and its alteration with.height does not give the necessary value of Pr(D).

Thus.. in the inventigation of that propagation, considerable attention has to be paid to experiments. The special characteristics of geograph- ical conditions of the territory involved should be taken into con- aideration during the analysis of experimental data and in their practical application because the conditions of propagation In arctic and tropical climates differ'from those existing over seas and*continento.

ORG.: Radiotechnology and Electronics Institute, AN SSSR, Moscow (Institut rad-ilotekhniki i elektroniki AN SSSR) TITLE: UHF waive propagation in the troposphere V/ SOURCE: Priroda, no. 12, 1965, 16-24 TOPIC TAGS: troposphere, UHF wave propagation, wave refraction, wave diffraction, wavegruide, millimeter wave, submillimeter wave, tropospheric radio wave, laser, wave scattering ABSTRACT: The authors review experimental and theoretical developments in the history of the study of UHF wave propagation in the troposphere, dividing the study into six periods. The first period covers the twenties and deals with primitive equipment and short-wave transmission, the second, extending through the thirties, with UHF waves, which were found to penetrate beyond the horizon line, leading to the development of the theories of refraction and diffractiorL. The Card 1 / 2 ACC NRt AP6016331 0 third period, covering the forties, is charactcrized by detailed elucidation of UHF wave propagration which evenlually led to the discovery of tropospheric waveguides and long-range tropospheric propagation. This was the beginning of the fourth period in the study of UHF wave propagation. The authors examine two of the theories on UHF mechanisms proposed at that time: incoherent and coherent scattering. They consider that a combination of the two to needed. The fifth period overlaps the fourth, as it goes back to prewar years. It is the period of the discovery of short, centimeter, millimeter, and submillimeter waves for which the troposphere is not a "transparent" medium. The authors consider the current sixth period as that of the development of research on UHF waves in the troposphere; it is closely related to the rapid development of laser technology.

AN'SSSR, Ser.-fiz., 4, 227 (1940)), the influence of Si on determination of Cu in Al-Cu alloys subjected to spark excitations is shown by.a sudden change in intensity at_.~2 weight ~Io. It was then ass 'umed thtrt a structural change in the alloy altered the conditions of entry into thq spark. To test this, the influence of a third element was studied in dependence on its concentration. The influence of the Si content on log(I Cu /I Ai ) d`epenOn in a complex manner on the ratio between NSiq the number of Si atoms, and NCd, the number of Cu atoms.

TITLE: The-Influence of "Third" Elements in the Spectral Analysis of Melted Metals With Condensed Spark PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheskayag 1959, Vol 23, Ur 9, pp 1093-1095 (USSR) ABSTRACT: In the introduction the disadvantages of a spectral analysis .1"ith solid test samples are first pointed out, and tuo ways are suggested for the purpose of avoiding these disadvantages. The first consists in Using the sample in form of a solution, and the second In carrying out an analysis of the'metal in melted state. The former method takes a long time. The latter was suggested by L. Ye. Vvedenakiy (Rafe It 2)1 it was!fioin that, in the case of melted eamplea, the effect of spattering the spark (obyskriianiye) and the influence of structure is avoided. The Influence exercised by "third" elements is in- vestigated in the prefient paper. In the measuring arrangement the ISP-22 spectrograph and the spark generator of the type IG_.2 were used in 'the oircuit according to Rayakiyj photometri- zAtion was oarried out by the microphotometer of the type 11.F-2. The experiments were carried out on a number of standard alloys of duraluming binary Al-Cu-alloya, and such additional- Card 1/2 ly containing 6,16 SL, as we'll as ort binary Al-Mg.-alloys and SOV/48--23-9-18/57 The Influence of "Third" Elements in the Spectral Analysis of Melted Metals With Condensed Spark such with an additIonal content of 5~ Zn. The reproducibility in these experimonte was found to be the same as in those carried out with solid tout aamplea, and the effect of spark spattering (obyakrivaniye) was completely eliminated in Cu, Fe, and SiI and.conaiderably reduced in Me, and Mn. At a tem- porature of 805 C the Influence of silicon in the coppero anal.- ysin in Al-Cu-alloys disappears. At a temperature of 770 C the influence of' zinb vanishes in the analysis of magnesium in Al-Mg-alloya.Su.,-omarizingly it is said that the analysis of melted duralumin samples may be developed to a degree of ex- actitude which cwresponds to that in the analyses of solid samples, that the influence of "third" elements may be avoidedg and that the errcr caused by the liquid state of the test sample may be avoided by an improvecent of photoelectric methods.
