战斗机红外对抗效能评估是**装备作战使用的关键，传统效能评估方法主要针对简单红外环境、固定作战态势和单一组件开展研究，不能充分反映红外对抗的真实性和全面性。基于此，提出了战斗机红外对抗效能评估方法，按照实战对抗过程，分成探测目标、占位和杀伤目标三个阶段进行研究，基于概率理论确定了不同阶段的概率权重，并建立了基于红外对抗全过程的效能评估方法，最终得到战斗机完成红外对抗任务的成功概率。对比分析结果表明了红外对抗效能评估方法的有效性和正确性，为战斗机红外攻击策略和防御策略的制定提供了理论依据。

The effectiveness evaluation of fighter′s infrared countermeasure is the key of operational use of weapon equipment. In allusion to simple infrared environment, fixed operational situation and single component, traditional effectiveness evaluation methods are researched, which can′t fully reflect the authenticity and exhaustiveness of infrared countermeasure. So the effectiveness evaluation method of fighter′s infrared countermeasure was put forward. The process of infrared countermeasure that was divided into three phases was studied in accordance with actual countermeasure process, such as detecting target phase, occupying phase, and killing target phase. The probability weights of different phases were confirmed based on probability methodology. And an effectiveness evaluation method based on infrared countermeasure whole process was proposed. At last, the success probabilities of accomplishing fighter′s infrared countermeasure mission were obtained. Comparisons show that the effectiveness evaluation of infrared countermeasure is valid and correct, which can provide theoretical basis for infrared attacking strategy and infrared defensing strategy.
