Abstract:
At present, the next generation weather radar in China is upgrading to the dual polarization system. The accurate measurement of differential reflectivity (〖WTBX〗Z〖WTBZ〗DR) of meteorological targets by the CINRAD/SAD dual polarization weather radar is an important part of parameter calibration. For Xuzhou dual polarization radar, 〖WTBX〗Z〖WTBZ〗DR calibration test for Xuzhou radar was carried out with UAV (Unmanned Aerial Vehicle) carrying two kinds of standard metal spheres, respectively. In this test, the VCPsect scanning mode was configured, the fan scanning combination of target azimuth ±5° was adopted and all radar filtering algorithms such as ground objects were turned off. The results show that the average value of 〖WTBX〗Z〖WTBZ〗DR was 0.265 dB, the minimum was -0.125 dB and the maximum was -0.375 dB, when the 40 cm metal sphere was used, and the distance between UAV and metal sphere was 68 m. The values of ZDR meet the technical requirements of radar 〖WTBX〗Z〖WTBZ〗DR calibration. The research provides a technical solution for operational radar to carry out dual polarization radar 〖WTBX〗Z〖WTBZ〗DR calibration.
