Abstract:

对于实际的多通道合成孔径雷达(SyntheticApertureRadar,SAR)系统,各接收通道响应之间不可避免地存在着一定程度的幅度和相位误差,为了得到较为满意的地面动目标显示(GroundMovingTargetIndication,GMTI)性能,通常都会在杂波抑制之前对通道间的幅度相位误差进行有效地校正.本文在基于回波数据相关矩阵特征分解的通道盲均衡算法基础上,结合降维处理技术及中值估计方法,提出一种稳健的多通道SAR/GMTI通道盲均衡算法.实测数据实验结果表明:与原通道盲均衡算法相比,本文所提算法不但收敛速度快,而且算法的有效性不受样本集中目标信号的影响.
