摘    要:采用长时间相参积累的方法对高速微弱目标进行检测的过程中,会出现距离走动和多普勒扩散问题。针对该问题,提出将Keystone变换和Dechirp结合的方法用于距离校正和多普勒补偿。通过理论分析和数值仿真表明,该方法具有较高的积累增益和检测性能。

关 键 词:距离走动  多普勒扩散  目标检测

Abstract:For detection of high-speed and weak targets, the long-term coherent integra- tion method is used in this paper. And a combination of Keystone transform and Dechirp is proposed to correct range migration and compensate Doppler spread. The theoretical deriva- tion and numerical experiments results show that a higher coherent integration gain and bet- ter detection performance can be achieved.
Keywords:range walk  Doppler spread  target detection
