Abstract

This paper proposes a novel method for MIMO-SAR ground moving target imaging in HRWS Mode. In order to compensate the periodically modulated error signal in Doppler history due to the radial velocity of moving target, the compressed sensing theory is used to estimate radial velocity in undersampled signal firstly. Then, the compensation signal is formed with radical velocity to remove error signal in the whole Doppler signal. Finally, ground moving target imaging is achieved by using focusing function of moving target. The numerical experiments are provided to demonstrate the effectiveness of the proposed method.
