摘要
主要研究了几种典型的多通道SAR杂波抑制技术:相位中心偏置(DPCA)技术、沿航迹干涉(ATI)技术和空时自适应处理(STAP)技术,探讨了对机载单天线SAR实际数据应用复图像域DPCA、ATI杂波抑制技术和空间频率域STAP杂波抑制技术实现运动目标检测,并给出一些实际数据的实验结果。
The paper focus on the study of several typical clutter suppression techniques for multi-channel SAR: Displaced Phase Center Antenna (DPCA), Along Track Interferometry (ATI) and Space Time Adaptive Processing (STAP) techniques. In the paper, it has been discussed that application of DPCA and ATI in the complex image domain for moving target detection in airborne single-antenna SAR real data as well as application of STAP in the space-doppler domain. In the end, some experimental results have been presented.
