Abstract

Space-surface bistatic synthetic aperture radar (SS-BSAR) has gained more and more researcher´s interests. In this paper, we focus on improving range resolutions of GNSS illuminator based SS-BSAR with the method of spectrum synthesis of ultra-wide-band (UWB). Narrow bandwidth signals, such as GPS P code, can be spliced into a wider signal. Simulation results show that it can effectively increase signal processing bandwidth, improve range resolution and target recognition capabilities.
