中文摘要：
提出一种波数域非匀速平台SAR成像方法.从波数和瞬时斜距的概念出发,通过对回波信号沿非匀速平台方位采样位置进行曲线积分得到理想的回波波数域表达式,再利用常规成像算法进行聚焦成像.该算法适用于任何已知平台方位采样位置的情况,不用进行插值操作,成像精度高.易于和已有成像算法结合.仿真结果验证了算法的有效性.
英文摘要：
A new algorithm is presented. Based on the concepts of the wave-number and instantaneous slant range, a precise 2-dimension （2-D） frequency analytical formula is developed by calculating the integral of the echoes along platform trajectory sampling positions, and finally the traditional imaging algorithm is used to focus the image. The algorithm suits any case if one knows the platform trajectory sampling positions, and it can obtain high precision for the absence of interpolation. This algorithm is compatible with the traditional imaging processing easily. Simulations show the validity of the algorithm.
