Embodiment Construction

[0023] The error registration method in the multi-radar system track fusion processing, using the comprehensive track position information fed back after the multi-radar system processing, the position information of the single radar track participating in the comprehensive track fusion processing, and the processing time information and other parameters The registration error of each single radar is calculated, and in the subsequent data processing, the registration error is used to correct the position of the single radar track, and then participate in the fusion process. The registration error is iteratively processed through three steps of fusion processing-error registration-correction (see FIG. 2 ).

[0024] When the multi-radar system is fused, the position of the integrated track is calculated by the weighted average of the positions of the relevant single radar tracks participating in the fusion. When calculating the weighted value of each relevant single radar, the d...

Abstract

The invention discloses an error registration method for track fusion of a multi-radar system, which comprises the following steps: calculating the registration errors of a single radar by using multi-radar integrated track information, the positioning information of single radar participating in the integrated track fusion, fusion time information and other parameters; and correcting the positions of single radar with the registration errors, and joining the corrected data to the fusion. Three steps of the fusion, the error registration and the correction are periodically performed, and registration error is subjected to iteration treatment. The invention can correct systematic errors and meet real-time requirement of track fusion of the multi-radar system.

Description

technical field [0001] The invention belongs to the field of data fusion and computer technology, and relates to data fusion and data analysis. Background technique [0002] Track fusion processing is a key technology in the air traffic automation system. The fused track position must have high accuracy to meet the needs of air traffic control / management. Among the factors affecting the accuracy of fusion processing, systematic error is a major factor, which is a deterministic error, which needs to be eliminated by error registration processing, so as to achieve the purpose of removing systematic error and improving the accuracy of fusion processing. [0003] The error registration methods mainly used now include the error registration method based on RTQC, the error registration method based on LS, etc. The error registration method based on RTQC is to project the detection values ​​of different radars on the same target into the same common two-dimensional coordinate sys...
