| 摘 要： | 为了提高极化合成孔径雷达(SAR)图像的舰船检测性能,提出了一种基于改进广义相对最优极化模型的极化SAR图像融合方法.改进的模型包含两个因子的乘积.第一个因子是最优极化状态下的雷达接收功率;第二个因子对应最优检测准则下的3个极化参数(极化熵、平面相似性参数、二面角相似性参数)的融合结果.使用该方法融合图像能够使得目标和...

| Abstract: | A modified generalized optimization of the polarimetric contrast enhancement(GOPCE) model was developed to improve the ship detection in polarimetric synthetic aperture radar(PolSAR) images.The model multiplies the radar receiving power for the optimal polarization state and the fusion of three polarimetric parameters,the Cloude entropy and two parameters associated with the desired target and clutter.The power difference between the targets and clutter is maximized in the fused image while the clutter vari... |
