Moving target modelling and indication in MIMO GEO SAR

The Journal of Engineering, 2019
Multiple-input multiple-output geosynchronous synthetic aperture radar (MIMO GEO SAR), composed by several mini-satellites in GEO orbits, has more spatial degrees of freedom, which helps to suppress clutter and improves the performance of ground moving ...
