| 摘 要： | 极化SAR运用地物目标的散射回波数据及天线收发两端的极化矢量合成功率图像。目标的相对最优极化（最优极化对比增强；OPCE问题）目的在于寻找一种收发极化状态而使得期望目标和背景杂波的接收功率对比度最大化。系统总结了SAR目标相对最优极化问题的解析算法与数值算法，对原有方法提出了一定程度的改进和新理解，并通过数据实验验证了算法的有效性以及合理性。

| Abstract: | Polarimetric SAR measures the echo data of ground targets in the form of complex scattering matrix, from which the polarimetricly synthetic image could be obtained with the join of transmitting and receiving Stokes vectors. The aim of the Optimization of Polarimetric Contrast Enhancement (OPCE) is to find a configuration of transmission and reception antennas to obtain the best contrast between the target and background clutter. This paper systematically summarizes the analytical and numerical algorithms, improves the existed methods and thoughts, and finally verifies their validity and rationality through data processing experiments |
