摘要
新一代的星载降水测量雷达将普遍采用双频与多极化工作模式,双频率、多极化星载降水测量雷达是遥感探测技术发展的必然趋势。鉴于此,深入研究了新一代双频率、多普勒与多极化星载降水测量雷达系统技术,对双频多极化星载降水测量雷达与机载演示验证系统进行了系统参数分析与设计,着重分析了系统工作频率、极化方式、扫描角度、脉冲重复频率与发射功率等关键参数的选择,推导了脉压系统的雷达气象方程,为开展空间降水测量雷达系统研究提供了技术参考。
The next generation spaceborne precipitation measuring radar will adopt dual-frequency and multi-polarization mode and this type of radar is the natural trend of remote sensing techniques. In this article, dual-frequency, Doppler and multi-polarization spaceborne and airborne precipitation measuring radar is studied and system parameters are analyzed, preparing for research on new generation of precipitation measuring radar. Key parameters such as frequency, polarization, scanning angles, pulse repetition frequency and transmitting power are analyzed in detail ,and meteorological radar equation for pulse-compression system is deduced.
