摘要
分析了雨的空间分布特性,对现阶段降雨测量雷达的现状进行了调研,提出了一种地球同步轨道星载降雨测量雷达设计方法。该雷达采用Ka频段工作频率,采用螺旋扫描实现5 000km直径的圆区域覆盖,可实现0.3mm/h以上强度降雨的探测。同时,地球同步轨道降雨测量雷达可实现定点观测,通过3~4颗卫星组网即可实现全球覆盖。该雷达是实现全球气候与环境变化监测,军事战场作战环境综合探测的必要装备。
The distribution characteristics of rain are analyzed,and the state-of-the-art of rain precipitation radar are investigated.The design method of a GEO satellite-borne rain precipitation radar is proposed.The radar uses Ka-band to realize rain detection,which can detect the rain whose intensity is above 0.3mm/h.Through spiral scan,it can realize 5000 km diameter circle area covering.Furthermore,the GEO satelliteborne radar can realize fixed-area covering.Through formation of 3~4satellites the global coverage can be achieved.So the proposed GEO satellite-borne rain precipitation radar can be applied in global meteorology environment monitoring and battlefield meteorology environment monitoring.
