摘要
该文研究了分布式卫星干涉合成孔径雷达(InSAR)系统中双基斜视雷达的CS成像算法,给出了算法的具体实现过程,并在算法实现中对分布式卫星InSAR系统的基线不稳定进行了补偿,消除了基线不稳定对SAR图像和干涉测量的影响。通过模拟仿真,验证了双基斜视CS算法的保相性以及基线不稳定补偿方法的有效性。
Chirp Scaling (CS) imaging algorithm is derived and implemented in this paper, which is adapted to bistatic and squinted radar in distributed satellites lnterferometric Synthetic Aperture Radar (InSAR) system. Considering the characteristic of baseline instability in this system, an effective method is proposed to eliminate the effect of baseline instability on SAR image and interferometric measure. The simulation results validate the property of phase preserving of bistatic and squinted CS algorithm and the effectiveness of compensated method of baseline instability.
