A New Target Detection Method Based on Multiple Jamming Cancellation Algorithm

Abstract:

This paper proposed a target detection method in the presence of multiple jamming, which may come from mainlobe or sidelobe of the array antenna. The jamming direction-of-arrival (DOA) is estimated using MUSIC algorithm, and a multiple jamming cancellation beamformer is suggested, which is based on a FIR filer in space domain, the beamformer is followed by a pulse compression filter in frequency domain which can improve the resolution in time domain. We take a simulation experiment for our method, considering a digital array radar with pulse compression technique, the experiment indicate that the target detection method have a good performance and can be used in digital array radar system.
