A new generation of fully coherent pulsed Doppler weather radar

Abstract

This paper describes the general performance and technical features, development and applications of a new generation of (C-band) fully coherent pulsed Doppler weather radar. The experimental results and future development approaches are given. The radar can not only measure accurately the radar reflectivity factor, but also the radial velocity component and velocity spectrum width of the echoes from rainfall particle group movement. It also provides dynamic parameters about storms for weather forecasts and identifies thunderstorm hazards by the distribution characteristics of the velocity field, and thus improves the calamitous weather warning and short-term forecasting capability.
