Abstract

Global precipitation measurement (GPM) is poised to be the next generation precipitation observations from space after the TRMM mission. The GPM will carry a dual-frequency precipitation radar (DPR), operating at Ku-band, and Ka-band frequencies. Since spaceborne precipitation observations have never been done in Ka-band before, extensive research work on dual-frequency radar, including electromagnetic wave propagation characteristics from space and retrieval algorithms are essentially required in developing system design and instrument performance evaluations. This paper presents a simulation-based study of Ku-and Ka-band radar observation of precipitations.
