Abstract
The performance of conventional space-time adaptive processing would deteriorated due to dense false-target jamming. Thus, a dense false-target jamming suppression method utilizing bi-phase random coded waveform is proposed. In the proposed method, the phase codes of bi-phase random coded waveform are generated by M sequence codes. Then the generated waveform is applied to the transmitting signal to reduce the correlation among coherent processing intervals. In the following, the matched filter is designed based on the transmitting waveform to suppress the jamming. Finally, the clutter is suppressed by jointly adaptive filtering in space and time domain. Simulation results verify the effectiveness of the proposed method.
