基于置信规则库推理的航母编队识别方法

本发明提出了一种基于置信规则库推理的航母编队识别方法,以在远程预警系统中对航母编队的识别为应用背景,首先基于航母编队中子目标的约束关系构建了航母编队识别置信规则库;然后基于该置信规则库采用证据推理算法实现了多层置信规则库的推理,并且研究了利用历史数据对置信规则库参数进行学习的方法,最后识别推理系统输出不同评价结果的置信度,从而达到对多种不确定性信息下的航母编队进行准确识别和早期预警的目的。本发明方案可以利用天波超视距雷达的输出信息实现对航母编队的识别和预警,对于天波超视距雷达的工程实际应用乃至远程预警系统的功能完善和性能提升具有非常重要的意义。

Aircraft carrier formation identification method based on belief rule base (BRB) inference

The invention provides an aircraft carrier formation identification method based on belief rule base (BRB) inference. The aircraft carrier formation identification method comprises the steps that with the identification to aircraft carrier formation in a long-distance early-warning system as the application background, firstly, an aircraft carrier formation identification BRB is constructed based on the constraint relation of sub-goals in the aircraft carrier formation; then, inference of the multi-layer BRB is achieved by an evidential reasoning algorithm based on the BRB, and a method for studying the parameter of the BRB through historical data is researched; and at last, an identification and reference system outputs the confidence coefficients of different evaluation results, and therefore the purpose of conducting accurate identifying and early-warning on the aircraft carrier formation under various different uncertainty information is achieved. According to the scheme of the aircraft carrier formation identification method, identification and early-warning to the aircraft carrier formation can be achieved through the output information of an over-the-horizon radar (OTHR); and the aircraft carrier formation identification method has very important significance to engineering practical application of the OTHR and functional maturation and performance improving of the long-distance early-warning system.
