Summary: 
The Tropical Rainfall Measuring Mission (TRMM) satellite has been observing successfully tropical and subtropical rainfall for more than 10 years since its launch on 28 November 1997. TRMM is equipped with the world's first active phased array type precipitation radar and has observed well three dimensional structure of various rain systems including typhoons. This paper introduces mission objectives of TRMM, outlines of the sensors, TRMM radar systems and data analysis and processing algorithms, some observation results (typhoon and latent heating), dual frequency precipitation radar on the Global Precipitation Measurement core satellite, which is to succeed TRMM, and the technological perspectives of spaceborne precipitation radar of the next generation.
