Description

technical field

[0001] The invention relates to a method for calibrating the phase center of a satellite navigation digital multi-beam transmitting array antenna, in particular to realizing the measurement and calibrating of the phase center of the array antenna by wireless spread spectrum pseudo-code ranging technology. Background technique

[0002] With the development of communication, radar, and satellite navigation technologies, the requirements for tracking and positioning accuracy of antennas are getting higher and higher. Searching and positioning by amplitude beams alone can no longer meet the requirements, and high-precision measurements must be based on the phase center of the antenna. and positioning. The deviation of the phase center will directly affect the accuracy of measurement and positioning. For precision measurement applications, this effect cannot be ignored. Therefore, it is necessary to test and calibrate the phase center before the antenna is used. ...
