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

摘要

The present invention relates to a method of correcting the reflectivity of a single-polarized radar using a right-handed system and a dual-polarized radar, and more particularly, to a method of correcting the reflectivity of a dual- The present invention relates to a method for correcting the reflectivity of a single polarized radar using a dual-polarity radar and a dual-polarity radar that calculates and corrects deviation of reflectivity data of a single polarized radar using data. According to the present invention there is provided a method of compensating for the reflectivity of a single polarized radar, comprising the steps of: obtaining a single polarized radar and reflectance data observed in both the right and dual polarized radar respectively; A second step of determining whether the reflectivity values of the obtained single polarization radar and the reflectivity data of the right-handed system are respectively larger than predetermined threshold reflectance values; If the reflectivity value of the single polarized radar and the right-handed system is higher than the critical reflection value according to the above discrimination, the deviation of the single polarized radar with respect to the reflectivity data is calculated based on the reflectivity data of the right- A third step of calculating a deviation of the single polarized radar with respect to the reflectivity data based on the reflectivity data of the dual polarized radar when the reflectivity is lower than the reflectivity value; And a fourth step of applying the calculated deviation to the reflectivity data of the single polarization radar to correct the calculated deviation.
