激光技术在主动红外对抗中的应用研究

Study on Laser Techniques Applied for Active IR Countermeasures

主动红外对抗技术是光电对抗领域中的一个重要分支。本文根据红外制导导弹和红外热成像装备的工作原理,阐述了用激光来对其进行干扰的两种模式,给出了干扰激光能量的计算方法,并通过试验对之加以印证。试验结果表明:较低的激光能量对红外装备进行干扰能获得很好的干扰效果,低功率的战术激光器在主动红外对抗中有着广泛的应用前景。

The active IR countermeasure is an important branch of the optoelectric countermeasures.Based on the analysis of working mechanism of IR guided missiles and IR imaging systems,two different interference types are illuminated.The calculation method of the needed laser energy is provided.Through the experiments we can draw such conclusions:Low laser power enjoys high performance for interfering IR armamed,and the laser with low power must be widely used in the active IR countermeasures.
