Abstract

Abstract: In term of the fundamentals of traditional Extended Chirp Scaling processing, a new CS Algorithm for along track mode Bistatic Synthetic Aperture Radar is presented, based on second order approximation of range history. The complexity of 2D Fourier transformation of signal impulse response, due to receiver-transmitter separation, is settled. It is a very precision image formation algorithm for along track Bistatic SAR system with small squint angles.

Key words: Synthetic Aperture Radar(SAR), Bistatic Synthetic Aperture Radar(BiSAR), Extended Chirp Scaling (ECS), Image Formation Algorithms.
