面源红外干扰的效果评定准则研究

Research on Effectiveness Evaluation Norms of Surface-type Infrared Jamming

面源红外干扰是用于对抗红外成像制导导弹的新手段之一。分析了红外成像制导导弹的工作过程及其目标识别机理。在对红外成像导引头实施干扰的目标识别阶段和目标跟踪阶段,对面源红外干扰的使用以及干扰效果的评定准则分别进行了研究,并评价了其有效对抗红外成像制导的能力。该评定准则以导引头的跟踪状态、跟踪误差或脱靶量为依据,通过统计干扰成功率实现对面源红外干扰效果的定量评价。这种评定方法简单合理,评定结果客观有效。

Surface-type infrared jamming is one of the new countermoves to infrared imaging guiding missiles. The operation process and target identification of an infrared imaging guiding missile are analyzed. The use of surface-type infrared jamming and the evaluation norm of its jamming effectiveness are studied respectively in both target identification phase and target tracking phase when the infrared imaging homing head is jammed. The ability of the surface-type infrared jamming to countermeasure infrared imaging guidance is evaluated. By taking the tracking state, tracking error and miss-distance as the basis, the evaluation norm implements the quantitative evaluation of the jamming effectiveness of the surface-type infrared jamming after the success rate of jamming is counted. This evaluation method is simple and reasonable. Its evaluation result is objective and effective.
