Geosynchronous parasitic SAR system is a kind of bistatic system,which uses a fixed ground-based receiver and a geosynchronous satellite as non-cooperative illuminator transmitting waves like television,FM broadcast or navigation signals.
地球同步轨道寄生SAR系统是利用地球同步轨道卫星传输的通信、导航等信号作为非合作照射源的一种双基地雷达系统,具有长时间观测目标区域、抗电子干扰、成本低等优势,有良好的发展前景。
