摘要

摘要: 多发多收星载SAR使用多天线从不同的相位中心发射正交编码信号，多个接收相位中心接收回波后形成多通道信号，显著增大了空间自由度，有利于地面动目标检测。该文研究了多发多收星载SAR空时自适应信号处理进行地面动目标检测的技术，针对星载SAR回波信号的特点，在研究空频自适应处理算法的基础上，使用基于特征值分解的空频自适应处理算法对多发多收星载SAR的杂波进行抑制，最后完成对动目标的检测。仿真数据处理结果验证了该文方法的有效性。

Abstract: Multi-input multi-output spaceborne SAR transmits orthogonal coding signals with multiple antennas from different transmitting phase centers, and receives returns from different receiving phase centers to form multi-channel signals. It can increase the spatial freedom considerably, which gives advantages to detecting ground moving targets. This paper researches the ground moving targets detection technologies for multi-input multi-output spaceborne SAR with space-time adaptive signal processing. Considering the characteristics of the returns of the spaceborne SAR, in the basis of research on the space-frequency adaptive processing algorithm, the text adapts eigen-structure based space-frequency adaptive processing algorithm to suppress the clutter and completes finally the detection of the moving targets. Simulation results proves the validity of proposed algorithm.
