摘要
论文首先从理论上简要阐述了星载海洋高度计海面回波的散射机理和回波信号后向散射模型;其后,利用M atlab数学工具,通过对我国“神州四号”飞船下传的大量高度计观测数据进行IQ采样数据提取、数据处理以及统计分析,进行了星载海洋高度计海面回波信号的统计特性分析与研究。
In the paper, the scattering mechanism of the ocean return signals from the spaceborne ocean altimeter and the backscattering model of the return signals were briefly described; By means of the Matlab tool, the Altimeter＇s IQ sampling data were isolated from a mass of scientific data received by the “ SZ-4” Spaceship, and the statistical characteristic of the ocean return signals from the Multi-Mode Microwave Remote Sensor （M3RS） Altimeter was analyzed by way of data processing and statistical analysis of the IQ sampling data.
