Data fusion method and device for ads-b and secondary radar monitoring information

Abstract

The invention relates to the track processing technology, in particularly, to an ADS-B and secondary surveillance radar monitoring information data integration method and device. With the object of solving the problems in the prior art, a data integration method and device are provided so as to realize the integrated tracking processing of ADS-B surveillance information and the secondary surveillance radar information, to make the tacking keep a constantly updated state and to ensure the continuity and the correctness of surveillance. The method comprises the following steps: converting the coordinates of different types of tracking information into a unified station-centered orthorhombic coordinate system; through the interpolation method or the extrapolation method, achieving time and space alignment and sending the processed point tracking information to a pre-processing point tracking line; from the pre-processing point tracking line, reading the point tracking information and using the local optimal proximity algorithm to have the determined tracking in the tracking line and the tentative tracking correlated; and finally, according to the tracking in the tracking line, performing extrapolation of tracking or removing the missing targets or the tentative track from the processing tracking line so as to maintain and protect the tracking.

Description

technical field [0001] The invention relates to track processing technology, in particular to a data fusion method and device for ADS-B and secondary radar monitoring information. Background technique [0002] The fundamental purpose of air traffic control is to enable aircraft on the route to fly in the airspace safely, efficiently and in a planned manner. Controllers need to monitor the dynamics of aircraft in the controlled airspace in real time. [0003] At present, the secondary radar (Secondary Surveillance Radar, SSR) system is generally used at home and abroad to monitor the aircraft dynamics in real time. The SSR system itself has many limitations: the straight-line propagation of the radar beam forms a large number of radar blind spots; it cannot cover the ocean and desert areas; the low frequency of the radar rotation cycle leads to slow data update, which limits the improvement of surveillance accuracy; Data such as the planned route and situation of the aircra...

AI Technical Summary

Problems solved by technology

The SSR system itself has many limitations: the straight-line propagation of the radar beam forms a large number of radar blind spots; it cannot cover the ocean and desert areas; the low frequency of the radar rotation cycle leads to slow data update, which limits the improvement of surveillance accuracy; Data such as the planned route and situation of the aircraft limit the improvement of tracking accuracy and the ability of Short Time Conflict Alert (STCA). Due to its own defects, the SSR system can no longer meet the requirements of today's air traffic control system, so it is necessary to develop a new monitoring tool

However, if ADS-B is only used as a means of surveillance, once there is a problem with the navigation system, the surveillance function will be lost, and the resources of the established air traffic control radar network will be greatly wasted.
