Abstract Signal to Noise Ratio (SNR) of the echo is critical for the detecting performance of sea ship in GEOsynchronous Synthetic Aperture Radar (GEOSAR) system. To address the low SNR problem of single pulse echo due to ultra-long distance between the satellite and sea ship, specific analysis of the improved SNR with coherent integration and its suffering from 3-D rotations of sea ship is carried out in this paper, corresponding conclusions are drew through processing of simulating and real data.
