恶劣气象条件对红外鱼眼跟踪系统影响的研究

随着战场空间的不断拓展和红外探测技术飞快发展,全空域的红外探测系统的威胁侦测成为提高已方武器系统生存能力的关键。然而,由于恶劣气象条件对红外的衰减作用,使得红外探测系统的作战效能受到了一定的影响和限制。文中基于红外鱼眼镜头的多目标跟踪系统,分别分析了霾、雾、雨、雪等恶劣气象对红外辐射衰减的衰减系数,以及衰减系数与能见度之间的相互关系,对各种不同气象条件的衰减效应进行了分析比较,并通过理论分析和实验得出了恶劣气象对鱼眼红外多目标跟踪系统的影响。

Study on the effect of harsh meteorologic conditions upon the infrared fish-eye lens tracking system

With the increasingly expanding of battle-space and rapid development of infrared detection technology, detecting the threats by the omni-spatial infrared detector system has been a key factor in ensuring the survivability of weapon systems. However the operational efficiency of the infrared detector system is limited because of the attenuation in the harsh conditions. A multi-target tracking system based on fish-eye lens was presented in this paper. We analyzed the relationships between the infrared radiation attenuation coefficients and the haze, fog, rain and snow respectively, as well as the relationship between the attenuation coefficient and the visibility, then compared the attenuation effects in different weathers. Theoretical analyses and preliminary tests have demonstrated the effect of harsh meteorologic conditions upon the infrared fish-eye multi-target tracking system.
