Correction method for reflectivity of single polarization radar using dual polarization radar

摘要

The present invention relates to a method for correcting the reflectivity of a single polarized radar, and more particularly, to a method of correcting the reflectivity of a dual polarized radar, Domain radar to compensate for the reflectivity of a single polarized radar using a dual polarized radar. The present invention relates to a method of correcting the reflectivity of a single polarized radar, comprising the steps of: obtaining the reflectivity data observed in a single polarized radar and a dual polarized radar respectively; A second step of correcting the reflectivity value of the obtained double polarized radar by using the reflectivity data, the differential reflectance data and the non-reciprocal phase difference data observed from the dual polarized radar; The reflectivity data of the single polarized radar for the observation altitude angle with the smallest observation altitude angle difference between the single polarized radar and the dual polarized radar are the same at the same distance between the single polarized radar and the dual polarized radar in the reflectivity data of the compensated dual polarized radar A third step of counting the number of samples of the reflectance data of the single polarized wave radar existing on the line; If the number of samples of the reflected reflectivity data is greater than the predetermined reference number of samples, then the reflectivity data of the compensated dual polarized radar on the same line at the same distance between the single polarized radar and the dual polarized radar and the reflectivity data of the single polarized radar If the number of samples of the number of reflected data is smaller than the predetermined reference number, then the reflectivity data of the corrected double polarized radar existing on the same domain including the single polarized radar and the dual polarized radar, A fourth step of calculating a deviation by comparing reflectance values of reflectivity data of the polarized wave radar; And a fifth step of applying the calculated deviation to the reflectance data of the single polarized wave radar and correcting the reflected wave by applying the calculated deviation to the reflectivity data of the single polarized wave radar.
