摘要
Active-Passive-Jamming (APJ) is formed by a chaff decoy reflecting jamming signals from an aircraft's active-ECM jammer. The effectiveness of APJ depends on many factors, one of which is the jamming signal's frequency feature. In this paper, we discuss and analyse APJ's frequency feature in a typical given offense-defense scenario for the case where the ECM jammer adopted is velocity gate pull off (VGPO), which is a kind of deception jamming technique. Our results show that the APJ's frequency feature depends not only on the jamming techniques of the jammer, but also on the Native Doppler Frequency (NDF), which is related to the relative positions, distances, angles and velocities of the jammer, radar and chaff decoy. We also carried out simulations, and the results show that the APJ mode can be useful for jamming an enemy radar.
