| 摘 要： | Cameron分解是一种非常重要的极化SAR目标相干分解方法,在舰船及小型飞机检测等方面有着广泛的应用.但由于Cameron分解方法未考虑目标可能具有的非相干特性,对包含非相干目标的场景应用会导致不准确的分解结果,不利于进行后续的目标检测处理.为了解决问题,通过引入Touzi提出的目标相干性判定准则,在Cameron分解过程中对目标进行相干分类预处理,能够较好地将场景中包含的非相干目标分离出来,从而提高了Cameron分解结果的准确性,达到了改进Cameron分解的目的.使用实测L波段极化SAR数据进行实验,实验结果验证了改进方法的有效性.

| Abstract: | Cameron decomposition is a significant method of target coherent decomposition for polarimetric SAR and is widely used for detecting ship and small airplane.Because of neglecting the incoherence the targets may have,using Cameron decomposition for the scene which includes incoherent targets will result in inaccurate outcome,and is disadvantageous to later processing of target detection.To settle this problem,target coherence criterion proposed by Touzi is introduced into Cameron decomposition for that probl... |
