Abstract

Low frequency ultra-wideband bistatic synthetic aperture radar (UWB BSAR) system is able to penetrate the foliage, get the high-resolution BSAR image, and offer the increased target information. In this paper, the low frequency UWB BSAR electromagnetic scattering characteristic is analyzed. First, the target under the foliage are modeled and discussed. Moreover, the method of moment (MoM) is proposed for the electromagnetic scattering characteristic. Finally, the simulation experiment is conducted for the modeling and analyzing of the electromagnetic scattering characteristic of the targets, which verifies the correctness of the low frequency UWB BSAR electromagnetic scattering characteristic.

低频超宽带BSAR电磁散射特性
低频超宽带双基地合成孔径雷达(UWB BSAR)系统能够穿透树叶,获得高分辨率的BSAR图像,并提供更多的目标信息。本文分析了低频超宽带BSAR的电磁散射特性。首先,对树叶下的目标进行了建模和讨论。此外,还提出了矩量法(MoM)来描述电磁散射特性。最后,通过仿真实验对目标的电磁散射特性进行建模和分析,验证了低频UWB BSAR电磁散射特性的正确性。
