Operational Evaluation of Edl Type IV Expendable Jammer. Ew Systems Test, Usaepg-3, Phase II, Equipment Test and Evaluation.

摘要

An evaluation is presented of the results of tests conducted to determine the operational feasibility of the EDL Type IV Expendable Jammer as a counter-countermeasure. The EDL Type IV that was used against Radio Repeater Set AN/TLQ2 and Electronic Countermeasures Set AN/MLQ-8 (XL-2) is a breadboard model. The tests include a bench test of battery life and power output. A ground-based EDL Type IV was then tested to determine the effective range for triggering two repeater jammers, the AN/TLQ-2 and the AN/MLQ-8 (XL-2). When repeater jammers are made to distribute their available power output among two or more signals simultaneously present in their pass bands, the effectiveness of the jammers detonating NVT Doppler-type fuzes is reduced. The ground-based EDL Type IV was tested with howitzer fire to determine the degree of protection it affords. Similar tests were conducted with an airborne EDL Type IV. Despite certain dificiencies of the breadboard model, the EDL Type IV is a feasible device for countercountermeasures against enemy VT fuze countermeasures equipment, particularly of the repeater type.
