摘要

A new and fast algorithm for MTI/MTD processing is presented. This algorithm is based on a formation of SAR images from each channel and using these for separation between moving and stationary targets. First, the problem is described by means of a generalized model. Then, an inverse problem is formulated and some of its approximate solutions by means of the Fourier transform are given. The approximate solutions are used to show how one can resolve stationary targets and moving ones completely regardless their distribution in space or reflectivity. The only criterion used is the velocity of a target. Further, it is shown how moving targets and stationary targets can be separated from processed, that is focused, SAR images.
