Analysis of Target Detection Performance on ENVISAT ASAR Alternating Polarization Mode
-
摘要: ENVISAT ASAR具有交替极化模式，可以提供3种双极化组合。该文针对3种双极化组合分别推导了几种目标检测器，包括最优极化检测器、白化滤波检测器、张量检测器、单通道检测器等，并使用ROC曲线对它们分别进行了性能比较。结果表明极化白化滤波检测器的性能最接近于理想的最优极化检测器，极大地提高了检测性能。

Abstract: The ENVISAT ASAR can operate on Alternating Polarization (AP) mode, which can provide three different dual polarization combinations. This paper derives target detectors for three different dual polarization combinations. The detection performance is compared using ROC curve. The results indicate that the Polarimetric Whiting Filter (PWF) detector is the best detector which approaches the performance of the ideal Optimized Polarimetric Detector (OPD) and can improve the detection performance. -
