| 摘 要： | 为检测和区分极化遥感SAR图像中的非平稳目标,讨论了极化SAR图像中两种非平稳目标的检测和区分方法。用极大似然比对固定朝向非平稳目标进行检测,用变化系数对周期表面非平稳目标进行检测。仿真结果表明,两种方法分别能把两种非平稳目标检测出来。

| Abstract: | To detect and discriminate two kinds of nonstationary targets,in this paper,the detection and discrimination algorithms of two kinds of nonstationary targets were proposed.By calculating maximum likelihood ratio(MLR),the oriented nonstationary targets were detected,and by calculating the coefficient of variance,the nonstationary targets with periodic surface were detected.Simulation results showed that the two methods have good detection performance for the two kinds of nonstationary targets respectively. |
