摘要

介绍Ｘ波段散射计辐射计组合系统的研制，利用这一组合系统可进行同时同地相继观测，得到ＶＶ，ＨＨ，ＶＨ，ＨＶ多极化的后向散射系数σ０ｐｑ，Ｖ和Ｈ极化的辐射亮度温度ＴＢｐ和地面热发射率ｅｐ。给出了树木地面背景以及有多种金属目标的σ０ｐｑＴＢｐ观测结果，并用一层随机介质散射辐射的主被动遥感理论进行了分析，为地面主被动联合遥感和背景杂波中目标识别提供了一个实例研究

Abstract

In this paper a novel system of the X band radiometer scatterometer developed by our Institutions is reported. By using this system

multi polarized （VV

HV） backscattering coefficients for active remote sensing and V

H polari zed brightness temperature for passive remote sensing can be measured simultan eously. Some measurements of scattering and emission from tree canopy with and without artificial metal targets are presented. Theoretical study of scattering and emission from a layer of random medium is discussed with data analysis. Ou r approach provides an example of correlated active passive remote sensing and application for target detection in environmental clutters.
