基于极化的浅埋目标体时域瞬态响应处理方法

摘要

To obtain the target feature information included by the time transient response,a new processing approach based on polarization is proposed.This method proves that the energy of surface reflection at different polarization is equal in early-time response stage.With computing the biggest singular of each window,the break time of the singular value is the begin-ning of the late-time response stage.The simulation results show that the proposed approach can separate the late-time re-sponse effectively.%为了获取瞬态响应蕴含的目标特征信息，提出一种基于极化的时域瞬态响应的处理方法。以早时响应中表面反射波能量相等为基础，计算加窗后各个数据窗下的最大奇异值，确定最大奇异值下降速率骤降时刻为晚时响应阶段的开始点。仿真结果表明，本方法能够实现对早时响应与晚时响应的分离。
