Abstract :
We investigate a framework for the detection of ground moving targets using a Multiple-Input-Multiple-Output (MIMO) radar system. We look at how phase histories collected from a MIMO Synthetic Aperture Radar (SAR) system can be used for target detection in a Ground Moving Target Indication (GMTI) mode while SAR images are being formed. We propose the usage of the recently developed Iterative Adaptive Approach to detect movers and estimate their velocities in the post-Doppler domain. We show how the waveform diversity afforded by a MIMO radar system enables its superiority over its Single-Input-Multiple-Output (SIMO) counterpart.
