The invention discloses a dual frequency band dual polarization spaceborne cloud-rain measurement radar system which is mainly composed of an antenna subsystem, a radio frequency subsystem, a digitalsubsystem, a monitoring subsystem and a power supply subsystem. The antenna subsystem adopts a parabolic reflector/microstrip reflective array antenna feeder system, and comprises a parabolic reflector/microstrip reflective array antenna, a Ka frequency band active phased array feed source, a W frequency band beam waveguide feed system and a Ka/W frequency band shared parabolic reflector/microstrip reflective array antenna. The radio frequency subsystem is connected with the Ka frequency band active phased array feed source, the W frequency band beam waveguide feed system and the digital subsystem. The digital subsystem is connected with a terminal. The system provided by the invention has the advantages that the three-dimensional vertical structure information of clouds and precipitationin the field of view can b
