Increasing self-protection jammer efficiency using radar cross section adaptation

Abstract

Increasing jamming effectiveness in self-protection electronic warfare systems is a crucial research area for air operations. Of all the factors affecting jamming performance, two parameters that increase jamming efficiency without changing the design parameters of radar and jammer systems are RCS and distance. Changing the distance between radar and target to increase the jamming effect is not sensible. Because disobeying the path for distance concern may ruin the operation aim. Adapting the RCS to the situation appears to be a suitable method to increase the jamming efficiency. In this study, a novel method is proposed for enhancement the jamming effectiveness by changing RCS appropriately. Hence, a heading calculator unit is integrated into the self-protection electronic warfare system. The heading calculator interacts with the radar warning receiver and jammer and points an appropriate heading direction during jamming. The heading variances are limited to as slight changes as possible.
