Problems solved by technology

Traditional methods have many limitations in use. For example, the method of using celestial constellations to calibrate the optical antenna must be carried out on a clear night with high visibility; the method of releasing the balloon has poor accuracy.
In the absence of an effective reference object, it is very difficult to correct the direction of the optical antenna, and the direction can only be guaranteed by the precision of the structural processing of the optical antenna. and supporting structures will be deformed at different levels, and these deformations will have unpredictable effects on the optical system

Description

technical field [0001] The invention belongs to the technical field of optical antenna calibration equipment, and in particular relates to a measurement system and a measurement method for an optical antenna emission angle. Background technique [0002] The calibration of the transmitting and receiving direction of the traditional optical antenna mainly depends on the reference object at a fixed position. Typical celestial body constellations can be used to calibrate the optical antenna, such as ballooning. Traditional methods have many limitations in use. For example, the method of using celestial constellations to calibrate the optical antenna must be carried out on a clear night with high visibility; the method of releasing the balloon has poor accuracy. In the absence of an effective reference object, it is very difficult to correct the direction of the optical antenna, and the direction can only be guaranteed by the precision of the structural processing of the optical ...
