Embodiment

[0027] Such as figure 1 As shown, in this embodiment, it includes an unmanned aerial vehicle platform 10 and a ground command center 20. The unmanned aerial vehicle platform 10 receives the control information of the ground command center 20, calibrates the antenna of the ground station to be measured, and sends the detection information Sent to the ground command center 20 to realize calibration of the UAV antenna. The UAV platform 10 includes a beacon instruction transceiver module 1, a calibration source and a UAV communication link 3; the calibration source is connected to the beacon instruction transceiver module 1, and the UAV communication link 3 is an air-to-ground two-way The data transmission channel transmits information for the beacon command transceiver module 1. The beacon command transceiver center is used to receive the control information of the ground command center 20 and send the antenna calibration information to the ground command center 20. The calibrati...

Abstract

The invention discloses an unmanned aerial vehicle based antenna calibration system and calibration method. The system comprises an unmanned aerial vehicle platform and a ground command center, and the unmanned aerial vehicle platform receives the control information of the ground command center, calibrates a to-be-detected ground station antenna, and transmits the detection information to the ground command center, thereby achieving unmanned aerial vehicle based antenna calibration. According to the invention, the unmanned aerial vehicle is used as a carrying platform for a calibration sourceand a calibrated antenna in the calibration system, the calibration source and the antenna are suspended at a specified height, and the calibration antenna on the unmanned aerial vehicle platform iswirelessly controlled by a ground remote control module to be aligned with the to-be-detected ground station antenna, and signal emission and processing are performed, so that the purpose of replacinga calibration tower in a complex ground environment is achieved, and the problem on how to dynamically adjust the height, frequency point, antenna azimuth angle and the like of a calibration signal is mainly solved.

Description

technical field [0001] The invention relates to a drone antenna calibration system and method, belonging to the field of intelligent control and intelligent detection. Background technique [0002] The receiving antennas of my country's satellite ground receiving stations are in various forms, including fixed and mobile, with diameters of 4.5 meters, 6 meters, 7.2 meters, and 12 meters. The main indicators to measure the quality of ground station antennas are: system quality factor (G / T value), antenna receiving pattern, antenna tracking performance, etc. At the same time, these performance indicators can also be used as a means of detecting system deterioration in daily maintenance. Therefore, satellite stations should regularly test these indicators, that is, antenna calibration. The current antenna calibration method has certain limitations, and some satellite ground stations have the problem of no tower calibration in actual conditions. Contents of the invention [0...
