概要

We developed a cloud profiling radar, named FALCON-I, transmitting frequency modulated continuous wave (FM-CW) at 95GHz. The radar can observe vertical radar reflectivity factor of clouds with high sensitivity and high spatial resolution. The observation of Doppler velocity is more necessary to know the inside structure of clouds and interaction with aerosol. Doppler velocities of clouds can be obtained from the phase shift of the signal by using double-FFT method. As a result of the observations at Chiba University, Doppler velocities of thin clouds were successfully obtained as well as of bright band, and rainfall.
