双基地合成孔径雷达 (BSAR) 一直是过去十年研究活动不断增加的焦点。这里介绍双基地SAR的广义模糊度函数(GAF)。首先，BSAR 的 GAF 在延迟多普勒域中表示，然后扩展到空间（坐标）域。从GAF中，可以提取有关BSAR分辨率的全面知识，包括距离和方位分辨率，以及BSAR分辨率单元的面积。这些一般结果还应用于几个特定 BSAR 几何结构的性能分析，包括空间-表面 BSAR (SS-BSAR) 系统，以证明这一新引入系统的潜在能力。
Bistatic synthetic aperture radars (BSARs) have been the focus of increasing research activity over the last decade. The generalized ambiguity function (GAF) of bistatic SAR is introduced here. First, the GAF for BSAR is represented in the delay-Doppler domain, and is then expanded to the spatial (coordinates) domain. From the GAF, comprehensive knowledge regarding the resolution of BSAR can be extracted, including the range and azimuth resolutions, as well as the area of a resolution cell of BSAR. These general results are also applied to the performance analysis of several particular BSAR geometries, including the space-surface-BSAR (SS-BSAR) system, to demonstrate the potential ability of this newly introduced system.
