Satellite alignment calibration method for phased array sensor

The invention relates to a satellite alignment calibration method for a phased array sensor. The method comprises the steps that corresponding alignment calibration strategies are selected according to the working modes of the sensor; if the orientation working mode is adopted in the sensor, the static alignment calibration strategy is adopted; orientation static alignment calibration is conducted on the sensor, and the sensor satellite alignment calibration is completed if a mission is ended; if the follow-up observation working mode is adopted in the sensor, the follow-up alignment calibration strategy is adopted; first, the sensor is subjected to comprehensive dynamic alignment calibration; within the orientation intervals of the follow-up work of the sensor, a series of alignment calibration points are collected at 6-10-degrree orientation intervals; orientation static alignment calibration is conducted on the sensor at each alignment calibration point, and the sensor satellite alignment calibration is completed if the mission is ended. According to the structural characteristics and the working modes of the sensor, corresponding system error alignment calibration modes and error models are adopted, the corresponding alignment calibration methods can be adopted according to the work modes in the working process, the calibration efficiency can be obviously improved, and the measuring precision of the sensor can further be effectively improved.
