Calibration method and system for dual-polarized phased array meteorological radar

The invention relates to a calibration method and system for a dual-polarized phased array meteorological radar. The method comprises the steps that unmanned aerial vehicles are controlled to enable the unmanned aerial vehicles and metal balls to present an unmanned aerial vehicle-metal ball-unmanned aerial vehicle 'V' shape in the air, the positions of the unmanned aerial vehicles and the metal balls are adjusted according to a positioning device, so that a connecting line between the two unmanned aerial vehicles is perpendicular to a radar beam, the two unmanned aerial vehicles are located at first null positions on the two sides of a main beam, and the two unmanned aerial vehicles are located at second null positions on the two sides of the main beam; the metal ball is located on the center line of the main wave beam, the dual-polarization phased array meteorological radar to be calibrated is controlled to carry out small-range horizontal sector scanning on the metal ball, after each scanning, the two unma
