Description
The Dual-frequency Precipitation Radar (DPR) is a spaceborne precipitation radar developed by the Japan Aerospace Exploration Agency. It operates in both Ku-band (13.6 GHz) and Ka-band. The Ku-band Precipitation Radar (KuPR) component is an enhanced iteration of the radar previously deployed on the Tropical Rainfall Measuring Mission (TRMM), offering improved sensitivity for detecting light rainfall and snowfall, particularly in mid-latitude regions. The KuPR features an antenna with a diameter of 1.83 meters, while the Ka-band Precipitation Radar (KaPR) utilizes a 0.71-meter diameter antenna.
