摘要 根据传统SAR处理中的扩展CS算法原理,推导了适用于同轨迹飞行模式双基地SAR的扩展ChirpScaling算法,解决了接收、发射分置引起的雷达响应函数从距离-方位域向二维频域变换的复杂性问题,分析了算法推导中各种误差的影响.通过计算机仿真验证了算法在小斜视角情况下,对双基地SAR数据成像的有效性. 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.
