Paper Abstract

A scheme is presented for ground moving target indication in multichannel synthetic aperture radar (SAR) systems. After the effect of different Doppler centroids is compensated, the spatial spectrum is symmetric around zero for a stationary scatterer but asymmetric around zero for a moving scatterer. Thus, moving targets can be detected through measuring the asymmetry of their spatial spectra. Moreover, since the asymmetry of the spatial spectrum can be measured directly in the spatial domain, the procedure of estimating the spatial spectrum is avoided and the computational efficiency is improved greatly. The effectiveness of this scheme is verified by both simulated and real SAR data.
