目前红外成像制导技术已在**领域得到了广泛的应用，它是通过探测目标与背景之间微小的辐射强度差异或辐射频率差异，形成目标与背景的红外图像，从而把目标和背景区别开来。在分析红外成像制导原理和特点的基础上，探讨针对红外成像制导的多种烟火干扰技术，重点阐述了烟幕干扰技术、面源红外诱饵干扰技术和强光干扰技术。

At present, infrared imaging guided missile technology has been widely used in military field, which detects small differences of radiation intensity or frequency between the target and the background, and forms the infrared images of the target and the background to distinguish the target from the background. Based on the analysis of the principle, advantages and disadvantages of infrared imaging guidance, passive jamming technologies for infrared imaging guidance are discussed. And smoke jamming, special material infrared decoy jamming and strong light blinding technologies are imposed.
