The invention discloses an angle calibration system of a phased array weather radar, the phased array weather radar is divided into an outdoor part and an indoor part, and the outdoor part comprises an antenna pedestal, an antenna array surface, an optical transmitter and a digital beam former. The indoor part comprises a signal processing server, a servo server, a health management server, a data processing server, a secondary product generation server, a cable, a cabinet and a network, the indoor part is provided with a GPS timing module, and an angle calibration analysis module and a sun angle real-time calculation module are arranged in the data processing module. The data processing unit is provided with an angle calibration coarse scanning task and an angle calibration fine scanning task, and is used for controlling the operation of the whole radar. The system is started through one key, calibration of the azimuth angle and the pitch angle of the radar is automatically completed, logs are automatically
