P. 67 (7 Pages)
Typical subsystem or “supercomponent” made by Microwave Electronics of Teledyne for electronics countermeasures (ECM) repeater contains two traveling wave tubes, gain equalizers and power supply. Supercomponents are coming Into increasing use in ECM systems because they simplify interfacing and offer improved performance.

P. 48 (6 Pages)
Installation of ALR-20 electronic countermeasures (ECM) receiver, shown in its entirety is expected to improve the ability of Strategic Air Command’s B-52 bomber crews to detect and counter hostile radar threats. Frequency, signal strength, signal modulation characteristics and relative indication of pulse repetition rates of threatening radars can be determined from ninetrace indicator display at right by the aircraft’s electronic warfare officer. The ALR-20 recently was flight tested by the Air Force in a B-52 at Eglin AFB.

which has 40 db. gain in the 1-60 me. range, is sample of thick film microcircuits being developed by Applied Technology Div. of Itek Corp. for application in company’s future reconnaissance and ECM systems. Company also is at work on wideband amplifiers covering the 30-100 me. and 100-500 me. range and precision tracking digital/analog networks.

P. 101 (3 Pages)
Navy simulation of Soviet SA-3 Low Blow radar at Naval Weapons Center duplicates electrical performance of the tracking/guidance radar for the Soviet low-altitude missile. Mimic Low Blow also closely resembles its Soviet counterpart with scanning antennas at right angles to one another and at 45 deg. to the ground plane. Two clipped parabolic sections, one at top, presumably for transmitting guidance signals, the other beneath it, for transmitting tracking
