Abstract

The invention discloses an antenna servo system calibration method based on coordinate rotation, and belongs to the technical field of antennas. According to the method, the tracking data of an antenna having a certain variation range within a certain period of time on a target with a known accurate position are used as sample data, and an antenna servo system errors is calibrated according to a calibration formula obtained via coordinate rotation by analyzing and calculating the sample data via the least square method. According to the antenna servo system calibration method disclosed by theinvention, the system calibration of an antenna servo system is achieved by analyzing the tracking data of the antenna on a target satellite, and the antenna servo system calibration method has the advantages of simple system structure, wide seat frame form range, low calibration cost, and capability of continuously improving the calibration precision by iterative calibration.

Description

technical field

[0001] The invention belongs to the technical field of antennas, and in particular relates to a method for calibrating an antenna servo system based on coordinate rotation. Background technique

[0002] With the development of communication measurement and control, the application market of antennas has expanded, and in most applications, it is required to achieve precise measurement and control of antenna pointing. In particular, in the fields of vehicle-mounted mobile communications, ship-borne and airborne satellite communications, most antenna moving carriers have navigation equipment or devices to provide more accurate carrier attitude and position, which provides favorable conditions for the moving carrier antenna to achieve pointing and tracking . In this case, in order to improve the pointing accuracy of the moving carrier antenna, higher system calibration requirements are put forward for the moving carrier antenna, but the calibration method in the...
