Abstract :
To remove the gain error caused by different waveforms and improve the performance of transmitting adaptive digital beamforming (TADBF), a reiterative matched filter (RMF) among different transmitted waveforms in Doppler domain is presented in this paper. Meanwhile, the drawback of RMF in time domain is analyzed. The simulation test shows that compared with the TADBF after matched filter (MF), the improvement of TADBF after RMF in Doppler domain on the quality of suppressing clutter is about 16dB.
