Distributed Multi-Antenna SAR Time and Phase Synchronization
Distributed multi-antenna SAR, in which the transmitter and receiver are mounted on separate platforms [279], will play a great role in future radar applications [218]. Compared to monostatic systems, such a spatial separation can offer many benefits, such as jamming and antiradiation weapons [416], as well as increased slow-moving target detection and identification capability via “clutter tuning” (in which the receiver maneuvers so that its motion compensates for the transmitter motion, creating a zero Doppler shift for the area being searched) [446]. This could be worthwhile, e.g., for topographic features, surficial deposits, and drainage, to show the relationships ...
