OPERATIONAL EVALUATION OF RADIO SET AN/TRT-2B (UNMODIFIED) EMPLOYED AS A VT-FUZE JAMMER
Abstract
T RESULTS OF AN OPERATIONAL EVALUATION OF Radio Set AN/TRT-2B (unmodified) as a VT-fuze jammer are set forth. The set is a swept CW jammer of about 150 watts maximum output, capable of AM modulation, and provided with a URA-T1 tone generator for audio tones, bagpipes, audio noise, and random MCW keying. Tests indicated that the equipment is readily set up and operated, is rugged, and can be transported in a 3/4-ton truck. The AN/TRT-2B was found to be highly vulnerable to electronic detection and direction finding. Experiments with Antennas AS-266 and AN/GLA-3 showed that the effect of ground reflec tion on the space pattern is a major and often unknown factor in the effectiveness of the AN/TRT-2B. The unmodified set was found unsuit able for jamming T-226E2 fuzes because of short time-on-signal. An expedient modification enabled the set to predetonate T-226E2 fuzes successfully beyond 4,000 yards and indicated a more elaborate modification which was undertaken. (Author)
