Efficient detection and ground mapping of selected moving targets using SAR raw-data
This work addresses moving targets detection and imaging using airborne SAR data. Targets are selected according to user-defined radial velocity and direction. The computational burden is drastically reduced because azimuth compression is done only for ranges with a positive moving target indication. Furthermore, the knowledge of the velocity sign allows to tune the detection and focusing of moving targets with higher SNR than the usual methods. Range migration is easily tackled because radial velocity is known, enabling the correct compression filter design.
