The two post-processing procedures for the R/V Mirai Doppler radar data using dual-PRF technique are developed. One is to correct the Doppler velocity data which is falsely-unfolded by dual-PRF real-time unfolding. The correction amount is determined by comparing target data bin to neighbor data bins. Another is to reduce second-trip echo in the reflectivity data, by detecting characteristic alternate pattern in dual-PRF observation. The parameters for the procedures are tuned by statistical method using observed dataset for tropical cloud system. Both procedures demonstrate good performance on the observed dataset by using tuned parameters.
