摘要

本文应用直接求散射体散射场的方法，运用Monte-Carlo模拟技术研究了植被电磁散射中由植被层的体散射和地面层的面散射相互作用引起的后向散射增强计算得到了不同高度的植被层的散射特性，给出了人们感兴趣的后向增强角宽度的量级．结果表明，在植被层较矮即地面影响较强时后向散射增强较大，由体-面相互作用散射引起的后向散射增强的角宽度较宽，约在10～40度之间.

Abstract

The backscattering enhancement due to the surface-volume interaction in a vegetation canopy is investigated in this paper by directly adding up the scattering fields of scatterers and applying the Monte-Carlo simulation technique. The results indicate that stronger backscattering enhancement occurs when the canopy layer is thinner. The angular width of backscattering enhancement due to the surface-volume interaction is of the order of 10

0 degrees.
