N2 - This paper proposes a mainlobe interference suppression method based on whitening filter for distributed array radar (DAR). Due to the equivalent large aperture of DAR, it is possible to cancel the mainlobe interference without target signal suppression. For narrowband signal, the time domain whitening filter (TD-WF) is used. As for the wideband signal or large aperture DAR, the target signals arriving at each antenna may have the envelope migration problem, thus the frequency domain whitening filter (FD-WF) is utilized in order to avoid this problem. In addition, a mainlobe interference suppression experiment is carried out in the scenario involving an S-band experimental radar system and an S-band jammer. The measured data is processed employing the proposed method, and the result verifies the effectiveness of this algorithm.
