Ground Moving Target Indication for MTMO-SAR
The multi-input multi-output synthetic aperture radar (MIMO-SAR) is an innovative concept,which can bring high degrees of freedom for SAR system with limited transmitting/receiving (T/R) elements.In this paper,ground moving target indication (GMTI) for MIMO-SAR is studied based on reasonable usage of the space-time equivalent samplings.Furthermore,this paper gives a deep insight of the azimuth spurious peaks effect,caused by the periodically modulated error signal due to the radial velocity of moving target. Also,the compensation method is given to suppress the unwanted spurious peaks.Finally,the numerical experiments are also provided to demonstrate the effectiveness of the MIMO-SAR GMTI.
