Research on application of unmanned aerial vehicles borne SAR

Synthetic Aperture Radar (SAR) has become one of the most important military equipments. And based on the virtues such as zero-casualty, low observable ability and low price, the field of unmanned aerial vehicles SAR(UAV-SAR) now gets more and more attention. This paper gives the summarization of UAV-SAR, introduces the foreign applications of UAV-SAR, both advantages and problems (as well as the countermeasures) are analysed in detail. At last, this paper shows the trend of UAV-SAR development in the future.
