Study on New Generation Spaceborne Rain and Cloud Measuring Radar System Techniques

双频率、多极化星载云雨测量雷达是遥感探测技术发展的必然趋势。深入研究了新一代双频多极化星载云雨测量雷达系统技术,给出了双频多极化雷达系统框图与主要指标,分析了天线子系统实现方案,提出了天线子系统的技术指标;考虑了中央电子设备子系统的实现方案,并计算了星载云雨测量雷达的数据率。该研究为开展空间云雨测量雷达系统研究进行了有益的尝试,可为我国未来空间云雨测量雷达的设计与研制提供参考。

Dual-frequency and multi-polarization spaceborne rain and cloud measuring radar is the natural trend of remote sensing techniques.Techndogies of new generation dual-frequency and multi-polarization spaceborne rain and cloud measuring radar are studied systematically.Radar block diagram and main parameters are presented.Antenna subsystem scheme is analyzed and antenna parameters are proposed.Central electronic device subsystem scheme is given consideration and data rate of spaceborne radar is calculated.This paper is a meaningful try for carrying out spaceborne rain and cloud measuring radar design,which provides reference to Chinese spaceborne rain and cloud measuring radar design and production in future.
