Dual-Polarization Weather Radars are fast becoming an important new tool in Doppler Weather Radar technology. When the dual polarization upgrade of the CINRAD/SA radar is completed, it will greatly improve the severe weather monitoring and warning ability of the meteorological service.

The WSR-98D/DP/S dual-polarization radar has many important features:

1.    Introduces in practice the results of many years of research into Dual-Polarization conducted on the American WSR-88D radar.

2.    Incorporates the technical approach of simultaneous transmission and reception of horizontal and vertical polarization.

3.    By extending the CINRAD/SA on line automatic built in calibration features to the dual polarization implementation, the system can ensure the accuracy of all Dual-Polarization measurements.

4.    Uses the same component structure as the American WSR-88D Dual Polarization implementation.

5.    Implements the same Volume Coverage Pattern (VCP) developed for the WSR-88D with Dual-Polarization.
