SVM-based low-altitude airspace navigation airplane conflict detection method

Abstract

The invention discloses an SVM-based low-altitude airspace navigation airplane conflict detection method which comprises the following steps of S1, constructing an SVM model through selecting a kernel function and parameters thereof; S2, obtaining information of an objective plane and a local plane, performing preprocessing on the information, and obtaining relative information of the objective plane and the local plane; S3, inputting the relative information of the objective plane and the local plane obtained through preprocessing into the SVM model, classifying the input relative information through the SVM model, and setting a predicated value according to the classification; and S4, performing weighted moving averaging on the predicated value in reference to a predication result of a previous time period for obtaining a final predicated value, and determining whether a conflict between the objective plane and the local plane exists according to the final predicated value. The SVM-based low-altitude airspace navigation airplane conflict detection method is used for performing conflict detection on the objective plane which is separated from the local plane by a relatively long distance and has advantages of effectively detecting the conflict between the planes in the low-altitude airspace, improving traffic gesture perception capability of a pilot in a low-altitude airspace flight environment, adjusting a flight plan in time and preventing the conflict.

Description

technical field [0001] The invention relates to a method for detecting conflicts of general aviation aircraft, in particular to a method for detecting conflicts of general aviation aircraft in low-altitude airspace based on SVM (support vector machine). Background technique [0002] In recent years, with the vigorous development of the aviation industry, the number of domestic aircraft is increasing day by day, the routes in the airspace are becoming more and more dense, and the flow of aircraft is increasing day by day, which causes the airspace to become more and more crowded, and congestion means conflicts. Whether it is an overly dense route setting, a malfunction of the aircraft itself or environmental factors such as wind, it may cause aircraft collisions. Due to the particularity of aircraft transportation, once an aircraft conflicts in the air, it is difficult to guarantee the safety of passengers and property. In addition, if the congestion cannot be effectively cl...

Problems solved by technology

[0004] However, there is no corresponding research on the problem of conflict detection in low-altitude airspace

The problem of conflict detection in low-altitude airspace is generally a short-term problem, the speed of the aircraft is relatively slow, the degree of freedom of flight is high, and the flight environment is complex

However, due to the uncertainty of the low-altitude airspace, it is difficult and uncertain to perform traditional linear extrapolation at long distances
