| 摘 要： | 研究叶簇对电磁波传播的影响对于雷达穿透叶簇探测隐蔽目标具有重要意义，根据国外超宽带雷达的外场实验，总结出叶簇穿透衰减和后向散射特性与频率、极化、俯视角等系统参数之间的关系，为我国的叶簇穿透UWB－SAR系统的频段与极化参数选择提供依据。

| Abstract: | The effects of foliage on electromagnetic wave propagation are important in the detection of targets hidden underneath foliage. Experiments data shows that foliage attenuation and backscatter are determined as functions of frequency, polarization and depression angle, which can be used as the base for the choices of system parameters in UWB SAR. |

| Keywords: | ultra wideband synthetic aperture radar foliage penetration progpagation attenuation backscatter property |
