One improved boundary process method for synthetic aperture radar (SAR) internal wave signal detection, which tries to reduce the errors during the extending process for empirical mode decomposition (EMD), has been introduced in this paper. This method is based on EMD and the criterion created by the theory that the max normalized deflection stands for the largest energy. The method was first applied both on several time series decompositions and on SAR nonlinear internal wave temporal series decompositions. The comparison of results showed that this method was more feasible and precise indicating that the method can detect the internal wave signals successfully from SAR image even with a lot noise.

SAR内波信号检测的一种改进技术

本文介绍了一种用于合成孔径雷达（SAR）内部波信号检测的改进边界处理方法，该方法试图减小经验模态分解（EMD）扩展过程中的误差。该方法基于EMD和由最大归一化挠度代表最大能量的理论创建的标准。该方法首先应用于多个时间序列分解和SAR非线性内波时间序列分解。结果比较表明，该方法更加可行，精确，说明即使噪声很大，该方法也可以成功地从SAR图像中检测出内波信号。
