Detection and imaging of moving objects with multichannel SAR system

It presents an approach of moving target detection by multichannel synthetic aperture radar (SAR), which the receivers displaced in heterogeneous arrays. The approach achieves the maximal unaliased band of radial velocities and Minimum detectable velocity, retains full resolution SAR images, the multiple measurement vectors were employed for improvement of the target focusing, and requires no increase in receiver samples. The proposed multi-channel synthetic aperture radar system and the associated signal processing are detailed, and the approach is numerically demonstrated via simulation and raw data experiments.
