Antenna device, mobile communication interference signal positioning method and system

Abstract

The present invention provides an antenna device, a mobile communication interference signal positioning method and a system. The antenna device includes: a directional antenna group for collecting interference signals, which is composed of four identical antennas arranged circumferentially on the same horizontal plane around the antenna central axis , and each adjacent antenna is perpendicular to each other; the GPS antenna is used to measure the position information and time information of the collection point; the three-axis gyroscope sensor is used to measure the angular velocity information of the reference antenna; the electronic compass is set on the axis of the antenna for When the central axis of the antenna rotates, measure the angle of motion direction of the reference antenna; the signal analysis module is set in the base at the bottom of the central axis of the antenna, and is used to process and analyze the collected interference signal through the DSP chip, and obtain the signal corresponding to the interference signal Waveform, and the data measured by the GPS antenna, three-axis gyro sensor and electronic compass, as well as the signal waveform are sent to the server for storage. The invention improves the positioning accuracy of the interference source.

Description

technical field [0001] The present invention relates to the technical field of wireless communication interference positioning, in particular to an antenna device, a mobile communication interference signal positioning method and a system. Background technique [0002] With the large-scale construction of 5G networks, all operators need to perform frequency clearing work during construction. Since the bandwidth of the 5G frequency band is wider than that of the previous communication system, some frequency bands are mostly involved in the re-cultivation of the previous frequency bands, resulting in a complex electromagnetic environment for the industry scenarios targeted by 5G. , so the current 5G frequency band is extremely vulnerable to interference. Therefore, how to locate the interference in the current 5G network construction is an important issue in the current 5G construction. [0003] Most of the existing wireless interference positioning adopts the following three...

However, this method is only applicable to fixed-point direction finding. When moving direction finding, when the received interference power of the two antennas is equal and it is not at the same point as the 180° rotation again, it is impossible to judge whether the incoming wave direction is on the angle bisector of the two antennas On the reverse extension of the bisector

[0004] From the above several existing interference signal positioning methods, it can be known that the location of the target interference signal in wireless communication is mainly fixed-point positioning. The results are also less accurate
