摘　　要：云和降水对全球的水和能量循环至关重要,是维持地球能量平衡的要素之一。星载云、降水雷达通过对云、降水主动探测,能够全天时全天候获取全球云和降水三维结构信息,可有效弥补气象卫星被动探测的不足。首先对星载云、降水雷达开展需求分析,总结了当前我国气象卫星云、降水雷达探测能力的不足;然后介绍了国内外星载云、降水雷达发展现状,归纳出我国星载云、降水雷达需解决的问题;最后给出未来我国星载云、降水雷达的主要发展方向。Clouds and precipitation are vital to the global water and energy cycle and act as crucial elements in maintaining the Earth's energy balance.Spaceborne cloud and precipitation radars can actively detect clouds and precipitation and obtain threedimensional structural information of cloud and precipitation globally all day and night,effectively filling the shortcomings of passive detection by meteorological satellites.Firstly,the demand analysis is conducted on spaceborne cloud and precipitation radars,summarizing the shortcomings of cloud and precipitation detection capabilities of current Chinese meteorological satellites.Then,the development status of spaceborne cloud and precipitation radars at home and abroad is introduced,and the problems that China's spaceborne cloud and precipitation radars need to be solved are summarized.Finally,we give the main direction of the development of spaceborne cloud and precipitation radars in China in the future.
