面向有源相控阵雷达的核心部件——T/R组件(transmit/receive module)，提出综合脆弱性评估概念及其数学模型表达，给出定量评估的博弈组合赋权-优劣解距离方法。首先，从元件和系统两个层次出发分别构建脆弱性评估标准:利用元件自身物理特性建立故障树，基于蒙特卡洛仿真计算得到运行状态的物理脆弱性指标(即可靠性指标);根据系统的电路结构，建立其拓扑网络，计算结构脆弱性指标。然后，提出融合物理和结构的综合脆弱性评估数学模型，建立博弈组合赋权问题优化组合权重，结合优劣解距离法实现对T/R组件综合脆弱性的定量评估。实验结果表明，T/R组件的综合脆弱性不仅与各元件固有的可靠性水平相关，更与其系统的电路网络拓扑结构密不可分，所建立的综合脆弱性评估模型能够有效合理地辨识其薄弱环节。
Vulnerability assessment of active phased array radar transceiver based on game combination weighting
For T/R(transmit/receive)module,the core component of active phased array radar,the concept of comprehensive vulnerability assessment and its mathematical model expression are proposed,and a quantitative evaluation method of game combination weighting-good and bad distance solution is presented.Firstly,the vulnerability assessment criteria are constructed respectively from two levels of components and systems.The fault tree is established by using the physical characteristics of components,and the physical vulnerability index(i.e.,reliability index)of operating state is obtained based on Monte Carlo simulation calculation.According to the circuit structure of the system,the topological network is established and the structural vulnerability index is calculated.Then,a mathematical model of comprehensive vulnerability assessment integrating physics and structure is proposed,and the game combination weighting problem is established to optimize the combination weight.The quantitative assessment of comprehensive vulnerability of T/R components is realized by combining the superior and inferior solution distance method.The experimental results show that the comprehensive vulnerability of T/R components is not only related to the inherent reliability level of each component,but also closely related to the circuit network topology of the system.The established comprehensive vulnerability assessment model can identify the weak links effectively and reasonably.
