Embodiment Construction

[0052] The core of the invention is to provide an external field antenna testing system. In the prior art, for the field antenna test, the antenna to be tested is usually fixed on the vehicle, the auxiliary antenna is erected in different positions as required, and the vehicle is used to perform circular and linear movements to realize the antenna test. However, this method is severely limited by the surrounding terrain and the accuracy of the vehicle's running trajectory, etc., with poor accuracy and high requirements for the working environment.

[0053] In the field antenna testing system provided by the present invention, the auxiliary antenna and related devices are loaded on the UAV, and then the UAV is controlled to move along the preset trajectory within the preset range of the antenna to be tested to drive the auxiliary antenna. Move and send the corresponding test signal to complete the performance test of the antenna to be tested. Drive the auxiliary antenna to mov...

Abstract

The invention discloses an external field antenna test system. The external field antenna test system is characterized in that an auxiliary antenna and the related devices are loaded onto an unmannedaerial vehicle, and then the unmanned aerial vehicle is controlled to move along a preset track within a preset range of an antenna to be tested so as to drive the auxiliary antenna to move and send acorresponding test signal to thereby test the performance of the antenna to be tested. The auxiliary antenna is driven by the unmanned aerial vehicle to move, only a certain space around the to-be-tested antenna is needed, and the requirement for the operation environment is lower. Meanwhile, the moving track of the unmanned aerial vehicle can be accurately controlled, so that the accuracy of theperformance parameters of the to-be-tested antenna can be greatly improved. The invention also provides an external field antenna test method which also has the above beneficial effects.

Description

technical field [0001] The invention relates to the field of antenna pattern testing, in particular to an external field antenna testing system and an external field antenna testing method. Background technique [0002] In the microwave anechoic chamber, various electrical performance parameters of the antenna can be accurately measured. However, after various antennas are deployed and applied, under the influence of various factors such as installation errors, electromagnetic interference, and surrounding obstructions, the actual electrical performance parameters of the antennas will be distorted, which will affect the performance of the entire system and affect the performance of modern large-scale array antennas. especially. Therefore, it is necessary to make a quick and accurate evaluation of the actual electrical performance parameters of the antenna in the external field to provide a basis for offset compensation and troubleshooting. [0003] In the prior art, for th...
