基于改良云模型的舰艇防空威胁评估

摘要

为了解决现有威胁评估模型存在不足，快速准确地对来袭空中目标进行威胁排序，提出了一种基于改良云模型的评估方法。针对舰艇防空作战目标特点，选取作战指标进行量化，对不同的定量指标和定性指标，分别采用离差最大化和改良云模型进行处理和赋权，通过Hamming距离计算贴近度，最后进行威胁综合排序。实例验证表明：该方法可以有效避免传统方法中人为确定各威胁指标权重的主观性，同时对定性指标的有效处理提高了评估准确性，为舰艇防空作战威胁评估提供了一条有效途径。%In order to solve the existing problems of threat assessment model,for fast and accurate threat sorting of incoming air target,an improved evaluation method based on cloud model is proposed. According to the target ship air defense operation characteristics,select operation target are quantified for different quantitative index and qualitative index,respectively uses the maximum deviation and improvement of cloud models to handle the empowerment,then the Hamming distance calculation of the degree of closeness of threat sequencing. The example showed that: this method can effectively avoid man-made determine the weight of each index of the threat of subjectivity in the traditional method, and the effective treatment of qualitative indicators to improve evaluation accuracy,an effective way for the ship air defense threat assessment is provided.
