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.
