Single-station mobile direction-finding positioning method

Abstract

The invention aims to provide a single-station mobile direction finding and positioning method, and the method realizes the position determination of a target radiation source by utilizing single monitoring direction finding equipment and an angle smoothing processing and probability accumulation statistical method based on a gravity center algorithm. The method mainly comprises the following steps: S1, acquiring, recording and storing data required by positioning; S2, preprocessing the acquired data; S3, generating a radiation source positioning statistical graph and estimating the position of the radiation source. Compared with the prior art, the direction-finding single-station mobile positioning method has the beneficial effects that a steady direction-finding single-station mobile positioning method convenient for software or hardware design implementation is designed by utilizing an angle smoothing processing and probability statistics technology of a gravity center algorithm, and the direction-finding single-station mobile positioning method has the characteristics of high positioning accuracy, low equipment and labor cost and high practicability.

Description

technical field [0001] The invention relates to the radiation source positioning field of radio signal monitoring direction finding and spectrum management technology, in particular to a single-station mobile direction finding and positioning method. Background technique [0002] Locating target emitters is a common business in the field of radio monitoring and spectrum management. This is very critical for radio interference investigation, positioning, and evidence collection. There are many radiation source positioning methods, the common ones are: using the direction finding results of multiple direction finding stations for cross direction finding positioning; using multiple monitoring stations to simultaneously collect signal data for TDOA time difference positioning; using single direction finding point motion measurement Cumulative orientation to the data. The first two methods require the cooperation of multiple monitoring stations / direction-finding stations, which...

Problems solved by technology

For the first two methods, the cooperation of multiple monitoring stations / direction-finding stations is required, which not only requires high technical requirements and hardware requirements for the cooperation between multiple stations, but also requires high cost of hardware facilities and consumes more manpower.

Although the cost of hardware facilities is reduced for the method of cumulative positioning using the motion direction finding data of a single direction finding point in the prior art, the positioning accuracy of the known methods in the prior art is not high
