PROBLEM :
At certain locations in the country there exists pulse modulated. electro-
magnetic radiation within a frequency band from 50 me to 40 kmcwhich would
be extremely valuable to detect, record, and analyze on a sampling basis, Un-
fortunately, these locations are normally inaccessible. and not conducive to
manned operation of conventional electronic collection equipment. It is
necessary, therefore, to develop a portable automatic data collection system
designed to circumvent:the physical limitations. thereby imposed.
OBJECTIVE:
It is the purpose of this task to develop the equipment needed to accomplish
.the automatic collection and temporary storage of data, as well as the equip-
ment necessary to provide for remote interrogation of the system and retrans-
mission of the collected data to the interrogating point, A special feature to
.be incorporated is a method for alerting the interrogator if.failure of system
operation occurs and also, if the installation has been disturbed by unauthorized
examination. The need for maximum reliability of system operation can be
readily appreciated.
DISCUSSION:
The planned system will be composed of a number of miniature equipments
which can be easily connected 'by flexible cable into various package configu-
rations.' Foreseeing the need for such a system, several basic equipments
have been developed, or are presently under development. Minor modification
,of these units may be necessary to adapt them to the system, but these changes
should present little difficulty. To simplify an understanding of the following
description of system operation, a block diagram is supplied on the attached
fold-out sheet. The equipments represented by separate blocks within the space
outlined in red pencil are those which will be furnished by the government.
The remaining blocks do not necessarily represent individual equipments, but
indicate the functions that the system must, perform.
SIMPLIFIED EXPLANATION OF SYSTEM OPERATION:
a) On a pre-programmed basis the programmer: (F) will close the power
circuit to the following a uipments: the crystal video receiver (C),
the signal actuate device (D), the time code generator (E), and
possibly the recorder electronics.
b) After power.is supplied and upon signal presence the signal actuate
.device will close the power circuit to the tape transport and the
incoming signal will be transferred to the recorder (G) channel No.
1 input. The. output from a 1000 cycle oscillator built into the
recorder will be recorded on the second track.
c) At the end of a pre-set "on-air's time (1-1/4 to 5 min.), the signal
actuate device tritggers the time code generator which then modulates
the 1000 cycle reference tone with coded time pulses. At this point,
two tracks of information have been recorded containing samples of
signals in. the area,, and the time of da': they were received. This in-
formation must now be transmitted to a remote point, 25 to 30 miles
distant, upon demand, I

Upon radio interrogation, the receiver (J) will trigger power to the
transmitter (I) and-rewind the recorded portion of tape at relatively
high speed. On rewind, the recorder must, first, play back to
modulate the transmitter (I) with the two data tracks; second, erase
the two tracks; and third, reset the system to its original signal
monitoring position..
When failure of some component equipment of the system occurs or when
the installation has been disturbed, as explained above, a coded
alerting signal will be transmitted by equipment (K). This equipment-
will answer the normal interrogation when trouble has been detected.
The apparent complexity of the system, increased by the need for minia-
ture equipment of low power consumption, lends itself to complete
development in possibly four separate phases. The first, study and
determination of approach; second, design and fabrication of an
engineering model of the recorder, the interrogating equipment, and
the data. relay equipment; third, fabrication of a prototype model of
the earlier engineering model, and design and fabrication of an
engineering model of the alerting equipment; fourth, fabrication of
a prototype alerting equipment and final system tests. Certain other
aspects of the approach to this problem must be guided by special
considerations.
SPECIAL CONSIDERATIONS:
1. The system described herein has been designation CS-11.
2. A most important consideration in the design of the system is its size
and power consumption. The largest single item of equipment shall
closely approximate outside dimensions of 5" x 3-1/241 x 3Pt. Power
consumption should be of a low enough magnitude to allow battery
operation from reasonably sized storage batteries for a period of 60
days. All of the,equipments to be supplied br the government meet
these qualifications.
preferably 1-7/8 ips. At this speed, a one-hour capacity and frequency
response within 3 db from 250 cps to 10,000 cps appears reasonable.
High speed playback is desired to compress the one-hour record time
to a 5 minute reproduce time. Much of the electronic design required
by this recorder will be supplied by the government.
The interrogation equipment will operate at a fixed frequency within
a 200 to 300 me frequency range. Operation on either of three specific
frequencies, to be determined at a later date, shall be accomplished
4. The CS-11 recorder shall be dual channel and record at a slow speed,
Temperature characteristics are set forth herein as a design goal;
the state of the art will definitely limit certain units for low
temperature operation. However, where possible, component units
will be designed to operate reliably from -40?C to +40?C. Storage
at temperatures from -60?C to +60?C shall not be detrimental to
operation,

by the simple insertion of crystals. The study phase is expected
to determine the most practical type of transmission to effect
communications. The distance between the collection site and the
interrogating site will be approximately 30 miles. Antenna(s) at the
collection site must possess omni-directional characteristics.
6. Normally, this system will operate from a storage battery chosen by
the contractor to provide maximum ampere - hour capacity per unit
volume, with special emphasis on size, weight, and temperature charac-
teristics. To provide for those instances where line power will be
available, an auxiliary power supply will be designed to operate
from AC or DC sources ranging in voltage from 70 to 270 volts and AC
frequencies from 50 to 400 cps. This supply must provide operating
power since it is assumed that space will not permit use of both
battery and line supply.
7, Of necessity, the interrogation receiver will remain on at all times,
interrogation cannot be pre-programmed.
8. The interrogating equipment (L), less the recorder, will be designed
for portable use. Permanent installation in automobiles, trucks,
.boats or aircraft shall be accomplished by appropriate shock mounted
cabinets and adapting power supplies at a later date.
9. Standard miniature connectors will be used throughout the system.
Mating connectors will be numbered and color coded for simplicit-,- of
system assembly,
10. The individual components and interconnecting cables will be water-
proofed to the extent that exposure to heavy precipitation for
periods up to 30 minutes will not be detrimental to operation.
11. Deliverable Items:
Phase I: Results of a study in the form of a technical specification
for . each. component equipment and a final report containing
an explanation of the conclusions evolved.
Phase II:
One engineering model of the basic CS-11 system including
the remote interrogating equipment, but excluding the
alerting equipment. This model shall represent the end
item in performance, and approximate the end item in size
and configuration.
Phase III:
One prototype model of equipment delivered under Phase II,
plus one engineering model of the alerting receiver/trans-
mitter. The prototype model shall fully represent the
desired end item.
