Due to left/right Doppler ambiguity, and the small difference in Doppler frequencies of adjacent points in flight direction, conventional monostatic SAR can not be used for forward-looking imaging. Then bistatic SAR with transmitter and receiver mounted on different platforms is coming into the eyes of researchers. In this paper, the feasibility of forward-looking imaging using airborne bistatic SAR...
Simultaneously real-time monitoring for several distributed areas of interest is getting important in many applications. Such as security guarantee system during Olympic Games and brushfire monitoring for power grid. However, current remote sensing systems can hardly meet such steep demands. In this paper, we introduce a brand new system of Balloon SAR with Multi-spotlight illuminate mode. The new...
A novel ground moving target detection and imaging model called Near-Space Slow SAR (NSS-SAR) is introduced in this paper. It is not only effective for fast-moving targets but also slow-moving and micro-moving targets, which is hardly possible for conventional airborne and spaceborne SAR. Meanwhile, this model only needs mono-channel to distinguish Doppler signature of moving targets from the competing...
