前视双基地SAR（Bistatic Forward-looking SAR)(BFSAR)是对双基地工作模式的一种拓展，能对飞行路线正前方区域进行较高分辨率成像，能消除侧视模式中存在的固有成像盲区，是传统侧视模式的重要补充，具有自身不可替代的优越性。因此对于前视双基地SAR的深入研究具有相当的价值。-Forward-looking Bistatic SAR (Bistatic Forward- & SAR) (BFSAR) is a kind of double base work mode of development, can be directly in front of flight path area of high resolution imaging, can eliminate inherent imaging side-looking mode existing in the blind area, is an important supplement of traditional side-looking mode, has its own irreplaceable advantages. So for the front of the further research of bistatic SAR is quite valuable.
