Title:
METEOROLOGICAL RADAR DEVICE, METEOROLOGICAL OBSERVATION METHOD, AND METEOROLOGICAL OBSERVATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/216086
Kind Code:
A1
Abstract:
[Problem] Even if Doppler velocity data include an incorrect value, to detect then incorrect value accurately. [Solution] A meteorological radar device 20 is provided with an approximation function calculating unit 121, an exclusion value detecting unit 122, and a data substituting unit 123. The approximation function calculating unit 121 calculates an approximation function using a plurality of items of Doppler velocity data arranged in an azimuth direction in Doppler velocity data being observed for a meteorological observation, obtained at each position represented by two-dimensional coordinates in a distance direction and said azimuth direction around the position of an antenna 200. The exclusion value detecting unit 122 detects an exclusion value using the plurality of items of Doppler velocity data arranged in the azimuth direction, and the values of the approximation function.
