Chaff Jamming Recognition for Anti-vessel End-guidance Radars

摘要

In order to solve the problem of chaff jamming recognition for end-guidance radar, average gray correlation degree (AGCD) is introduced here to analyze the difference of time-domain correlation characteristic between vessels' echo and clutter. A novel recognition method called position matching is presented making use of the difference of spatial position between vessels and chaff cloud. Finally, recognition method based on micro-Doppler effect is provided according to the difference of movement. Simulation experiment and theory study indicate the effectiveness of the three methods.
