Abstract

The invention discloses a plane space positioning system and method for a radio signal interference source. The method comprises the following steps: at least three paths of radio signals of the radiosignal interference source can be collected from at least three signal receiving antennas via a USRP device, Labview platform software is used for storing the three paths of radio signals in a cacheregion of a computer in a form of IQ modulated data, the three paths of IQ modulated data are read from the cache region so as to form radio signals collected via two groups of signal receiving antennas, an MUSIC algorithm is used for processing radio signals collected via the two groups of signal receiving antennas so as to calculate angles formed by the two groups of signal receiving antennas and the radio signal interference source, two rays are drawn respectively at the calculated angles from a middle point of a line between the two groups of signal receiving antennas, and an intersectionpoint obtained via intersection of the two rays is used as a measured and determined position for the radio signal interface interference source. Via implementation of the plane space positioning system and method, a specific position of the radio signal interference source can be accurately determined.

Description

technical field [0001] The invention relates to the technical field of troubleshooting radio signal interference sources, in particular to a plane space positioning system and method for radio signal interference sources. Background technique [0002] Troubleshooting sources of radio signal interference is an important technique. In a complex electromagnetic environment, it can promptly and quickly find illegal users (such as illegal stations, pseudo base stations, etc.), and perform radio signal source interference direction finding and positioning, which is a prerequisite for implementing radio control. However, due to the complex electromagnetic environment of the radio, the existing radio signal interference source investigation is complicated to operate on the radio signal interference source and the positioning is not accurate enough, it is difficult to accurately locate the specific location of the radio signal interference source, resulting in The positioning is not...
