摘要 提出了两种原始数据域的双通道SAR-GMTI实现方法.DPCA-Radon方法可以完成无杂波情况下的运动目标检测和估计,DPCA-Frft-ATI方法可以完成受杂波“污染”运动目标的检测和径向速度估计,该方法提高了信杂比,提高了目标检测和估计性能,优于通常的原始数据域方法,也优于图像域的方法,并且可实现运动目标的聚焦以及图像域的重新定位.仿真结果证明了其正确性和有效性. The paper proposes two raw data based approaches for two aperture SAR-GMTI. The method of DPCA-Radon suecessfully detects and estimates parameters of moving targets in clutter-free environment. The method of DPCA-Frft-ATI achieves these purposes in clutter-rich environment and performs superiorly than commoly used raw data based method and image-based detector via improvement of signal to clutter ratio, also it can focus and relocate moving targets. Simulation results indicate feasibility and effectiveness of the methods.
