Coherent Radar Networks: Terminology, Synchronization, and Applications

IEEE Journal of Microwaves
In coherent radar networks, multiple radar sensors not only operate cooperatively but also facilitate coherent evaluation of signals from other spacially distant radar units.

Analysis and Simulation on Imaging Performance of Backward and Forward Bistatic Synthetic Aperture Radar

Remote Sensing, 2018
In recent years, bistatic synthetic aperture radar (SAR) technique has attracted considerable and increasing attention. Compared to monostatic SAR for which only the backscattering is measured, bistatic SAR expands the scattering measurements in aspects ...
