Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that this fusion method is relatively rough, and does not consider the accuracy difference of each radar and the time difference of information detected by each radar, so the fusion accuracy is not high, which in turn affects the monitoring of aircraft

Embodiment Construction

[0035] The specific implementation manner of the invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] see figure 1 , the embodiment of the present invention provides an aircraft monitoring method based on the fusion of multi-radar information, the method comprising:

[0037] 10: Determine whether the aircraft corresponding to the received first radar information has historical radar information;

[0038] 11: If it exists, calculate the weight w of the information to be fused for the first radar information,

[0039] w=a*w trend +b*w time +c*w priority (1)

[0040] Among them, w trend Trend weight of information to be fused, w time is the time difference weight, w priority is the priority weight of the radar corresponding to the first radar information, a, b, and c ...

Abstract

The invention relates to the field of aviation management, in particular to an aircraft monitoring method and device based on multi-radar information fusion. The method includes the steps that whether historical radar information exists in an aircraft corresponding to received first radar information or not is judged; if yes, the to-be-fused information weight of the first radar information is calculated; according to the to-be-fused information weight of the historical radar information and the to-be-fused information weight of the first radar information, to-be-fused information of the first radar information and the historical radar information are fused into radar fusion information; the aircraft corresponding to the radar fusion information is monitored. The to-be-fused information of the first radar information and the historical radar information are fused according to the to-be-fused information weight of the first radar information and the to-be-fused information weight of the historical radar information, fusion precision of multiple pieces of radar information in the same aircraft is greatly improved, and accordingly the aircraft can be monitored more clearly and more specifically.

Description

technical field [0001] The invention relates to the field of aviation management, in particular to an aircraft monitoring method and device based on fusion of multi-radar information. Background technique [0002] At present, air traffic control basically relies on radar surveillance. Due to the small coverage of single radar surveillance, the position accuracy of the monitored aircraft is low. Therefore, modern air traffic control systems use multiple radars to monitor aircraft. Multi-radar surveillance It can expand the coverage area of ​​the surveillance airspace, improve the surveillance accuracy of the aircraft, and increase the credibility of the surveillance results. [0003] In a multi-radar monitoring system, multiple radars will scan the same aircraft at the same time. Due to the independence of each radar and the influence of time difference and accuracy when scanning, if the information of each radar is directly output, it will be seen on the radar screen. An ai...
