Abstract :
Based on the generalized sidelobe canceller (GSC), we propose a novel reduced-rank beamspace post-Doppler adaptive beamformer, where the blocking matrix are replaced by an architecture that consists of the novel combination of space-time channels. The number of space-time channels required by the new method is very small. Simulation results in ideal situations and with limited sample are presented. The approach can cancel clutter while maintain low sidelobe more efficiently. It has low sample support requirement, strong robust and convenient implementation. Performance analysis is carried out using simulated data. The results prove the effectiveness of the proposed approach.
