摘要

传统合成孔径雷达(SAR)不能对前视方向进行成像;双基地SAR(BSAR)可以解决这一问题。介绍了一种双基地前视SAR(BFSAR)结构。采用序列反演法(MSR)获得其二维谱，然后在此谱的基础上使用反尺度傅立叶变换算法(SCFT)。仿真结果验证了该方法的有效性。

Focusing of Translational Variant Bistatic Forward-Looking SAR Based on Inverse Scaled Fourier Transformation Algorithm

The conventional synthetic aperture radar (SAR) cannot image in the forward-looking direction; this problem can be solved by bistatic SAR(BSAR). A bistatic forward-looking SAR(BFSAR) configuration is introduced in this paper. The series inversion method (MSR) is adopted to obtain its 2D spectrum, and then the inverse scale Fourier transform algorithm (SCFT) is used based on this spectrum. The simulation results verify the effectiveness of this method.
