Recently, the developments of multi-parameter SAR systems are so fast. Those images are of multi-bands,
multi-polarizations, multi-look-angles, multi-resolutions and multi-swaths and so on respectively in order to meet the
different needs from ocean, atmosphere and land users. The safeties and operations for the ships over sea surface offer
important supports based on real detection from satellite SAR. So, Satellite SAR remote sensing methodology is of great
potential for monitoring ships.
The research areas of the paper include satellite SAR developing states and its progresses, SAR imaging mechanisms and
studied techniques for ship detection, example research and compare their results by the approach and tradition. The
studies indicate that the monitoring technology for ship provided by the studies is of important application values and
