神舟4号多模态微波遥感器散射计分系统

SZ-4 Scatterometer Mode of Multimode Microwave Sensors (CNSCAT/M^3RS)

介绍神舟4号多模态微波遥感器散射计分系统的研制情况和在轨实验情况。首先简单介绍了系统组成、工作特点以及机载校飞实验,随后介绍了数据处理过程以及遥感器地面信号处理系统的研制开发工作,给出了在轨海面风场测量的实验结果以及亚马逊热带雨林的后向散射系数测量结果。

We introduce in this paper the Scatterometer mode of Multimode Microwave Sensors on board Chinese Shenzhou-4 unmanned spacecraft launched on Dec. 29, 2002. We first introduce the system components, characteristics and airborne experiment simply, and then, initroduce the data processing and system simulation in detail. We also present the measured wind field during flight experiment and the radar backscattering coefficients over the Amazon rain forest.
