A new method for three-axis wind field retrieval on multiple radar environment is proposed. The proposed method is designed especially to retrieve z-axis velocities in low altitudes with high accuracy by considering spatial correlation of wind velocities. A numerical simulation showed its advantage that the proposed method estimated z-axis velocities at a low altitude of 1500 m where the traditional...
A probabilistic attenuation correction technique for differential reflectivity ZDR, based on the Bayesian theory, in a dual polarization networked environment is proposed. The proposed technique assumes a proportional relationship between specific differential attenuation ADP and specific differential phase KDP, and a power law relationship between backscattering differential phase δco and ZDR. The...
Raindrop size distribution (DSD) retrieval algorithm for a weather radar network consisting of X-band dual-polarization weather radars is proposed. This algorithm is based on a DSD retrieval method for a single-radar (SRR), which is elaborated in our paper of the SRR, “RAINDROP SIZE DISTRIBUTION (DSD) RETRIEVAL FOR X-BAND DUAL-POLARIZATION RADAR” in this conference. The SRR outputs an ML solution...
Ku-band broadband radar is a short-range (15 or 20 km) high-resolution (range and temporal resolution of several meters and 1 min per volume scan with 30 elevations) weather radar to resolve fine structures of precipitation from the near surface (several tens of meters), and a networked observation with several Ku-BBRs covers the troposphere accurately and efficiently. In this paper, two latest observation...
A new high-resolution Doppler radar, called Ku-band broadband radar (BBR), with fast scanning capability for meteorological application has been developed. Due to the new system design, the BBR can accurately measure the radar reflectivity factor with a range resolution of several meters and a time resolution of 55 s per volume scan from the nearest range of 50 m to 15 km for 10-W power using pulse...
