Method for calibrating antenna angle of millimeter-wave weather radar

The invention discloses a method for calibrating an antenna angle of millimeter-wave weather radar. The method comprises specific steps as follows: step one, a millimeter-wave weather radar antenna angle calibration platform is put up and comprises an industrial control computer (1), a theoretical sun position determination module (2), a sun position measuring module (3), an antenna angle processing module (4), an antenna controller (5) and a signal processor (6); step two, the theoretical sun position determination module (2) determines the theoretical sun position; step three, the sun position measuring module (3) controls the measuring sequence of the sun positions and acquires time, antenna angle and atmospheric noise data; and step four, the antenna angle processing module (4) processes the acquired data and determines and calibrates the error of the antenna angle. Accordingly, the calibration of the antenna angle of the millimeter-wave weather radar is realized. By means of the method, the calibration of the antenna angle of the millimeter-wave weather radar can be conveniently and rapidly finished, the calibration can be performed at any time as required, and the accuracy and the high quality of observation data are guaranteed.
