烟幕对红外和近红外等波段的电磁波有吸收、反射和散射等特性,可以导致红外成像制导导弹导引头接收到的能量大大衰减,从而降低导弹命中率。在综合分析烟幕对抗红外成像制导导弹复杂过程的基础上,建立了系统仿真模型,包括作战效能主模型、基于烟幕消光机理和红外成像制导原理的对抗模型以及其它辅助模型。进一步对干扰效果进行了仿真试验,动态仿真了烟幕对抗红外成像制导导弹的态势,得出了烟幕布放战术决策的原则和方法。
The smoke absorption, reflection and scattering characteristics of the infrared and near-infrared electromagnetic waves can cause the attenuation of the energy received by the infrared imaging guidance missile seeker greatly, thereby reducing the missile hit rate. Based on the comprehensive analysis of the complicated process of smoke-guided infrared guided missile, a system simulation model is established, including the main model of operational effectiveness, the confrontation model based on smoke extinction mechanism and infrared imaging guidance, and other auxiliary models. The interference effect is further simulated and the situation of the smoke screen confronting infrared imaging guided missile is simulated dynamically. The principle and method of tactical decision of smoke screen placement are obtained.
