Imaging of moving targets with SAR based on space-time two dimensional signal processing

Based on the space-time two dimensional signal processing, this paper proposes a new method for the imaging of moving targets with SAR by using the equivalent space-time echoes of an array antenna. This method, which is much more effective for detecting and imaging targets whose radial velocity is very much smaller than a single antenna, has no blind area of velocity and can provide a high-resolution image of the slowly moving targets. The computer simulation results illustrate its availability.
