Abstract

Chirp Scaling (CS) algorithm is derived and implemented in this paper, which is adapted to bistatic and squinted radar in formation flying satellites interferometric synthetic aperture radar (InSAR) system. Considering to 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 squint CS algorithm and the effectiveness of compensated method of baseline instability.
