Abstract

The invention relates to a remote-controlled calibration device in the field of aerospace measurement and control, in particular to a remote-controlled calibration device applied to the angle calibration and zero range calibration of a Ka frequency band-based large antenna measurement and control system. The device comprises a Ka frequency standard source reception and process module (1), a system monitoring module (2) and a communication module (3), wherein the signal input end of the Ka frequency standard source reception and process module (1) receives a signal from a Ka frequency band master antenna (4) and the signal output end thereof is connected with the system monitoring module (2) through the communication module (3) in a manner of remote interactive transmission after the signal is processed. The technical proposal can complete the angle calibration and zero range calibration of a Ka frequency band measurement and control station and meanwhile, realize the remote control of the remote-controlled calibration device which is convenient and flexible to be controlled and used.

Description

technical field [0001] The invention relates to a remote control calibration device in the field of aerospace measurement and control, in particular to a remote control calibration device for angle calibration and distance zero value calibration based on a Ka frequency band large-scale antenna measurement and control system. Background technique [0002] At present, most of the domestic USB antennas are 10m-12m antennas, and the far-field conditions in the S-band are generally about 2km. Generally, the calibration equipment is installed on the calibration tower, and the calibration tower is generally 50m-100m. The distance from the main antenna is 1km to 2km, and the calibration equipment and the system monitoring station are connected by communication cables. [0003] However, the antenna of the Ka-band measurement and control station is a 15m antenna, and the far-field condition is about 40km. To meet the elevation angle of 1.6 degrees, the height of the calibration tower ...
