基于ECMDA-EN的空战目标威胁评估
Aerial combat target threat assessment based on ECMDA-EN
摘要
Abstract
The situation information obtained in the environment of strong confrontation air combat is often accompanied by error,missing and other defective data.Due to the relatively fixed model and pa-rameters and the lack of targeted information correction links,the existing air combat target threat as-sessment methods are prone to lead to the distortion of the threat assessment results at the relevant time.A target threat assessment method of evidence correction and model dynamic adjustment evidential net-work(ECMDA-EN)was proposed.Firstly,based on the classification of mutant,continuous and defi-nite types of evidence information,four kinds of evidence correction methods were designed combined with the degree of predicted information defect.On this basis,the sample data was constructed by sum-marizing the air combat confrontation trajectory under different combat intentions,and the defect data correction method based on a LSTM neural network trajectory prediction model was proposed.Finally,a dynamic adjustment scheme of network node weights and model was designed according to the dele-tion of evidence nodes.Simulation results show that the proposed method solves the problem that the traditional threat assessment method rely too much on the reliability of information by effectively pro-cessing the defect information and automatically adjusting model,and can continuously provide reason-able threat assessment results.关键词
