摘要：
A new millimeter wavelength vertical weather radar system has been developed. It uses pulse compression technique and has the characteristics of more than half of duty factor with 5 W solid-state power amplifier. Nonlinear FM waveforms based on Blackmanharris function at transmitter are generated for range sidelobe suppression. We successfully obtained equivalent radar reflectivity and Doppler mean velocity and these were compared with MRR at moderate rain events for the system verification. (C) 2011 Wiley Periodicals, Inc.
