Abstract

In conventional ISAR system, when the requested resolution of radar is high, while the size of target is large, it will cause the Migration Through Resolution Cell(MTRC), it will also exist the same problems in Bistatic ISAR systems. This paper analyzes and discusses the reason of causing MTRC particularly in the module of Bistatic ISAR, and compares it with the situation in Mono ISAR systems. And then a correction algorithm based on Keystone transformation is presented in the paper, which eliminates the MTRC in the targer imaging, Finally, some simulation results are given to validate the validity of the algorithm.
