Application of Digital Radio Frequency Memory in Noise Jamming of Pulse Doppler Radar

Qiu Jiang

Abstract

The noise jammer using digital radio frequency memory(DRFM)technology,has the features of high frequency spot accuracy,narrow noise bandwidth and high jamming power efficiency,is effective in jamming against pulse Doppler(PD) radar.This paper introduces the component and the operation principle of the jammer using DRFM,and analyzes the emergence of frequency spot error and spurious signal,and their influence on the jamming noise.
