一种基于速度等效的空变模式双站SAR 成像处理算法
n Equivalent Velocity-Based Spatial-Variant Bistatic SAR Imaging Algorithm
虽然双站合成孔径雷达（SAR，synthetic aperture radar）处理是当前SAR研究中的热点，但现有研究主要集中在空不变模式双站SAR，而空不变模式双站SAR高精度成像处理仍然没有得到很好解决。针对这个问题，提出了一种基于速度等效和非线性CS（Chirp Scaling）算法的空变模式双站SAR成像算法，并以星载发射机和近空间飞行器载接收机为例作了仿真分析。
lthough bistatic syntetic aperture radar (SAR) has received much attention in recent years, the focus is placed on spatial-invariant bistatic SAR and the imaging formation algorithms for spatial-variant bistatic SAR is not well resolved. In this paper,we propose an equivalent velocity and nonlinear CS (chirp scaling) combined image formation algorithm for spatial-variant bistatic SAR imaging. Taking spaceborne transmitter and near-space vehicle-borne receiver as an example, we perform extensive simulation analysis.
