Abstract

Embodiments of the present invention relate to an antenna fault detection method and apparatus. The apparatus comprises: a sweep source, used for generating a first sweep signal and a second sweep signal; a first directional coupler, used for generating a first coupling signal from the second sweep signal; a second directional coupler, used for performing coupling processing on the first coupling signal, generating a second coupling signal, transmitting the second coupling signal through an antenna, performing coupling processing on an antenna reflection signal used for the antenna to receive the second coupling signal, and generating an antenna coupling reflection signal; a radio frequency amplifier, used for generating a first reflection signal after amplifying the antenna coupling reflection signal; a delayer, used for delaying the first reflection signal, and generating the first delayed reflection signal; a mixer, used for mixing the first sweep signal and the first delayed reflection signal to generate a mixed signal; and a signal processor, used for processing the mixed signal generated by the mixer, and obtaining fault information of the antenna.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for detecting antenna faults. Background technique [0002] With the rapid development of mobile communication, active antenna system (Active Antenna System, AAS) is increasingly widely used in communication, satellite navigation and aerospace measurement and control and other fields. [0003] The active antenna system uses radio frequency multi-channel technology to control the vertical and horizontal sub-arrays of the antenna, and flexibly controls the vertical and horizontal beams of the antenna, thereby improving the coverage quality of wireless signals and improving network capacity. the goal of. [0004] At present, in existing solutions for detecting active antenna faults, a standing wave detection circuit is added to detect antenna faults. The standing wave detection method adopts the method of detecting the power of the transmitted radio freq...
