Abstract:

We proposed a new algorithm for range-Doppler estimation in PBR within the framework of sparse recovery in compressed sensing. By using a simulated scenario, we show that the algorithm is effective to reduce the masking effects of strong targets over weak ones. In addition, we have implemented the PBR system to collect real data and validate the proposed algorithms based on the real data. Compared with the conventional beamforming, our proposed method has better estimation performance for direct path. When the beam we observe and the beam of the direct path are too closed, compared with the beamforming, more number of frames can be observed using our proposed method. Since the effect among the target has been reduced, the M-OMP has better estimation performance for range-Doppler-angle estimation compared with the conventional MF method, especially for DOA estimation.
