Correction of Multi-Target Range Migration Based on Keystone Transform
摘要
Abstract
In weak target detection, migration through range cells(MTRC) of high-speed targets would affect the performance of long time coherent accumulation and thus should be corrected first. For the deficiency of the usual Keystone algorithm on correcting multi-target MTRCs with different ambiguity factors, an improved algorithm is proposed in this paper. After the basic Keystone transform without considering the velocity ambiguity, a fast method is applied to find out all targets' ambiguity factors. In this way, each target's migration is corrected respectively to its motion, so the coherent time can be increased and the coherent accumulation gain can be improved. Performance of simulations verified the value of the proposed algorithm.关键词
