Method and system for determining threat degree of non-cooperative target flying at low altitude to desired place

Abstract

The invention provides a method and system for determining the threat degree of a low-altitude flight non-cooperative target to a desired place, and the method comprises the steps: obtaining the continuous coordinate data of the low-altitude flight non-cooperative target in a certain period of time through taking the coordinate of a set desired place as a reference; and determining the threat degree of the flight non-cooperative target to the desired place according to the coordinates of the flight non-cooperative target and the change condition of the coordinates in the continuous time. Threat judgment and auxiliary decision making can be performed on various low, slow and small targets such as an unmanned aerial vehicle, a balloon, a kite, a Kongming lantern and a flying bird which possibly threaten the safety of important targets in a protection area of a desired place; by utilizing the threat determination method provided by the invention, the determined threat generated by the flight non-cooperative target is provided for the command and control system, so that the automation and intellectualization of auxiliary decision of a command information system can be improved, the decision time of a commander is shortened, and the strike efficiency of a defensive system is improved.

Description

technical field [0001] The invention relates to the field of methods for determining the threat of non-cooperative targets, in particular to a method and system for determining the threat level of low-flying non-cooperative targets to key locations. Background technique [0002] The rapid development of UAV technology makes its commercial application more and more extensive. At the same time, some people with ulterior motives maliciously use drones as a new method to carry out illegal activities, scouting important military sites, passing prohibited items, photographing confidential facilities, carrying explosives for purposeful sabotage activities, etc., serving the country, military and Public safety poses a serious threat. [0003] The current supervision methods for unmanned aerial vehicles are not complete, and there is no stable and reliable mature system application. In order to ensure safety, some important points of military and government agencies mostly use pers...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem of judging the threats of existing UAVs to important places, especially the problem of sorting the threats to such targets when multiple or a large number of "low, slow and small" targets approach at the same time, the present invention provides a low-altitude flying non-cooperative The method of determining the threat level of the target to the important place, identifying and judging the potential target with possible maliciousness from the target group, obtaining the expression value of its threat intention, and providing a quantitative basis for the commander's decision-making and disposal
