摘要:

针对相控阵雷达作战效能评估中战场环境等不确定因素的影响, 采用改进Dempster-Shafer(D-S)证据理论对其进行作战效能评估方法的优化。首先, 通过构建相控阵雷达作战效能评估指标体系, 明确评估指标并赋值权。其次, 引入Kulsinski差异和模糊熵方法, 对传统的D-S证据理论进行改进, 减少指标在融合过程中的融合权重不确定性的影响。最后, 通过改进D-S证据理论对评估指标进行数据融合, 建立评估准确性较高的相控阵雷达作战效能评估模型。通过算例验证分析, 所提方法能够有效减少融合过程中的不确定性影响, 可实现相控阵雷达作战效能评估的目的, 提高作战效能评估精度。

Abstract:

Aiming at the influence of uncertain factors such as battlefield environment in phased array radar operational effectiveness evaluation, the improved Dempster-Shafer (D-S) evidence theory is adopted to optimize the operational effectiveness evaluation method. Firstly, the evaluation index system of operational effectiveness of phased array radar is established, and the evaluation index is defined and the assignment weight is given. Secondly, Kulsinski difference and fuzzy entropy method are introduced to improve the traditional D-S evidence theory and reduce the influence of the uncertainty of the fusion weight in the indexes fusion process. Finally, by improving the D-S evidence theory to fuse the evaluation indexes data, the operational effectiveness evaluation model of phased array radar with high accuracy is established. Through the verification and analysis of numerical examples, the proposed method can effectively reduce the influence of uncertainty in the fusion process, which achieves the objective of phased array radar operational effectiveness evaluation, and improve the accuracy of operational effectiveness evaluation.

Key words: phased array radar, Dempster-Shafer (D-S) evidence theory, operational effectiveness evaluation, Kulsinski difference, fuzzy entropy
