基于极化的浅埋目标体时域瞬态响应处理方法

A processing approach of time transient response for buried target based on polarization

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。

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.
