Spaceborne Video-SAR moving target surveillance system

Video-SAR combines SAR imaging and video techniques together, enabling continuous surveillance of a specific area, which is a new developing microwave detection technology. Several airborne Video-SAR achievements have been published; however, less attention has been paid to the moving targets in the Video-SAR as well as spaceborne platforms. In this paper, the continuous observation problem of spaceborne Video-SAR is solved by multi-relay-receivers mode and the geostationary transmitter can cover a large scene uninterruptedly. A sketchy describe of a spaceborne Video-SAR system performance parameters is presented. An airborne Video-SAR simulation is carried out to testify the effectiveness of this system.
