Carrier Formation Recognition Method Based on Confidence Rule Base Reasoning

Abstract

The present invention proposes an aircraft carrier formation identification method based on confidence rule base reasoning. Taking the identification of aircraft carrier formations in the remote early warning system as the application background, firstly, the aircraft carrier formation identification confidence rule base is constructed based on the constraint relationship of sub-targets in the aircraft carrier formation. ; Then based on the confidence rule base, the evidence reasoning algorithm is used to realize the reasoning of the multi-layer confidence rule base, and the method of using historical data to learn the parameters of the confidence rule base is studied. Finally, the confidence of different evaluation results output by the reasoning system is identified, so that To achieve the purpose of accurate identification and early warning of aircraft carrier formations under various uncertain information. The scheme of the present invention can use the output information of the sky-wave over-the-horizon radar to realize the identification and early warning of the aircraft carrier formation, which is of great significance for the practical engineering application of the sky-wave over-the-horizon radar and the improvement of the function and performance of the remote early warning system.

Description

Carrier Formation Recognition Method Based on Confidence Rule Base Reasoning technical field The present invention relates to a kind of detection and tracking information using sky-wave over-the-horizon radar (Over-the-Horizon Radar, OTHR) in the long-distance early warning system, proposes a kind of aircraft carrier based on belief rule base reasoning (Belief Rule Base, BRB) Formation identification technology is an effective research program applied to the identification and early warning of aircraft carrier formations in long-range early warning systems. Background technique As the main equipment of the long-range early warning system, sky-wave over-the-horizon radar (OTHR) has a distance coverage of 800km to 3500km. It has the ability of long-distance continuous monitoring of low-altitude aircraft and sea surface ship targets. At present, there is no other system that can replace it. However, the detection and tracking output of OTHR is the track information of a serie...
