Abstract:

A bidirectional, multi-level threat-assessment framework is proposed for engagements against mixed swarms of aerodynamic and ballistic targets, addressing the inability of current methods to reconcile target-type heterogeneity and to quantify swarm scale and cooperative effects. The framework establishes an index system that integrates adversarial threat attributes, key-area defense effectiveness indices, and global correction factors. Intrinsically static attributes are evaluated via Pythagorean fuzzy entropy combined with TOPSIS, while dynamic attributes are fused through grey relational analysis and TOPSIS. A global correction factor explicitly quantifies swarm scale, cooperative gains, critical target types, and higher-echelon intelligence to recalibrate threat attributes. The relative relationship between adversarial threat attributes and defense effectiveness indices finally yields an integrated threat value for each target. Simulations demonstrate marked improvements in accuracy and operational utility for mixed-swarm threat assessment, providing a reliable basis for optimal resource allocation and efficient interception decision-making.

Key words: Pythagorean fuzzy numbers, TOPSIS, grey relational analysis(GRA), integrated air defense and missile defense, global correction factor

摘要:

针对气动目标与弹道目标混合集群来袭场景下,现有威胁评估方法难以有效兼容目标类型差异及量化集群规模、协同效应的问题,提出一种敌我双向视角的多层次威胁评估框架。该框架构建包含敌方威胁属性、要地防御效能指数和全局矫正因子的指标体系;评估方法上,固有属性采用毕达哥拉斯模糊熵结合TOPSIS法,动态属性融合灰色关联与TOPSIS法,并引入全局矫正因子量化集群规模、协同增益、关键目标类型及上级情报等协同特征以修正威胁属性;结合敌方威胁属性与要地防御效能指数的相对关系,计算各目标综合威胁值。仿真验证表明,该方法显著提升了混合集群目标威胁评估的准确性与实用性,为战场资源优化配置与高效拦截决策提供了可靠支撑。
