Abstract

The invention discloses a method and a device for implementing direction finding and positioning of an interferometer. The method for implementing direction finding and positioning of the interferometer includes: solving multiple direction finding results of the interferometer, classifying the direction finding results by the aid of the regularity time trend of the direction finding results, computing positioning results of the classified direction finding results and finally solving a distribution probability circle of target positioning results. According to the technical scheme, the method and the device for implementing direction finding and positioning of the interferometer have the advantages that the step of classifying the direction finding results by the aid of the regularity time trend of the direction finding results is added before the positioning results of the direction finding results are computed, and thereby a false positioning set generated by fuzzy direction finding results is decreased, computing pressure can be reduced remarkably, and accuracy degree and stability degree for solving the positioning results can be enhanced remarkably.

Description

Technical field [0001] The invention relates to the technical field of radio direction finding, in particular to a method and device for realizing direction finding and positioning of an interferometer. Background technique [0002] The interferometer direction finding positioning system performs N times direction finding on the same target on a relatively stationary ground at different positions within a period of time, and calculates the intersection of all the direction finding results on the earth including the fuzzy results, and only one of them is true Point, theoretically in N times of direction finding positioning, the intersection point that coincides N times is regarded as the target position, see Figure 1-a ; In the actual situation, due to the error of direction finding and the attitude and position of the interferometer direction finding and positioning system, the points that should be coincident with the target point walk around the target point or scattered around ...
