Abstract :
The hybrid mode provides radar images with resolution better than in stripmap mode with swath length longer than in the spotlight mode. In the paper described is a processor for hybrid radar data. The algorithm bases on the chirp scaling algorithm. In order to process the hybrid mode data an azimuth filter is applied before the chirp scaling algorithm.
