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 three-dimensional 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.
