摘　　要：在建立雷达目标的单频多极化幅度响应方程的基础上,提出了运用极化分集技术和线性化最小二乘法提取目标极化本征系数的方法,此组系数是与目标的姿态角无关的绝对极化不变量,亦即目标的极点。最后以哑铃型目标为模型进行计算机仿真研究,结果表明这种极化雷达极点特征抽取算法是有效可行的。This thesis based its theory on the construction of single frequency multi-polarized amplitude response equation of radar target, and uses the technology of polarized diversity and the means of linear least squares to extract the polarized essential characteristics of the target, which is the absolute polarized invariable nothing to do with the position angle of the target, that is to say, the invariable is the pole of the target. Finally, the simulation is performed on the basis of dumbbell-formed target. The result explained that this kind of pole characteristics extracting algorithm is feasible.
