We developed an adaptive polarimetric target detector (APTD) to determine the optimum combination strategy for a multichannel polarization-sensitive optical system. The proposed algorithm is based on scene-derived polarization properties of the target and background, and it seeks to find an optimum multichannel combination of linear polarizing filters that maximizes the signal-to-clutter ratio (SCR) in intensity and Stokes parameter images. The algorithm is validated by performing RX anomaly detection and a generalized likelihood ratio test on both synthetic and real imagery. The experimental results are analyzed through calculated SCR and receiver operating characteristic curves. Compared with several conventional operation methods, we find that better target detection performance is achieved with the APTD algorithm.
我们开发了一种自适应极化目标探测器（APTD），以确定多通道偏振敏感光学系统的最佳组合策略。所提出的算法基于目标和背景的场景衍生偏振特性，旨在找到线性偏振滤波器的最佳多通道组合，以最大化强度和斯托克斯参数图像中的信杂比（SCR）。通过对合成图像和真实图像进行RX异常检测和广义似然比检验来验证该算法。通过计算得到的SCR和接收机工作特性曲线对实验结果进行分析。与几种传统操作方法相比，我们发现APTD算法具有更好的目标检测性能。
