Impact analysis of DRFM-based active jamming to radar detection efficiency

Abstract

The influence of DRFM active jamming technology on pulse compression coherent radar is studied here. By establishing radar signal detection model and introducing radar equation, the influence of signal produced by DRFM on the detection performance of radar receiver is analysed, and the relationship between radar detection probability and interference power is obtained. Finally, the effective index for judging the jamming effect is summarised, and the range of effective jamming signal power is determined.
