Rainfall intensity estimation method using observation data of K-band dual polarization radar at short distance

摘要

A method for estimating rainfall intensity using multi-height observation data of an ultra short range double polarized radar is disclosed. A step of receiving the non-differential phase difference, the horizontal reflectance and the differential reflectance, which are scan observation data, of the multiple altitude observation data of the ultra short-range dual polarization radar by the observed altitude angles, and the horizontal attenuation Calculating a vertical attenuation for each scan from the horizontal and differential reflectances of the multiple elevation observation data, calculating a volume average of the horizontal attenuation for each scan, a volume of vertical attenuation for each scan, Calculating a volume average of the average, the input non-uniformity phase difference, a volume average of the horizontal reflectance, and a volume average of the differential reflectance, a volume average of the horizontal attenuation, a volume average of the vertical attenuation, And estimating a rainfall intensity using at least one of a volume average of the plurality of rainfall intensity distributions and a volume average of the differential reflectance.
