Abstract :
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 microDoppler effect is provided according to the difference of movement. Simulation experiment and theory study indicate the effectiveness of the three methods.
