末敏子弹的红外成像实验方法

摘要

According to the detection and recognition of terminal sensitive projectile for the infrared detection and warning system, and the infrared radiation characteristics of Terminal Sensitive Submunition (TSS) with a parachute was investigated by using the high-resolution infrared thermal imager. The thermal battery was activated inside the body of TSS, and the static infrared image sequences were generated by monitoring in real-time with the infrared thermography. Further, when the TSS is throwing from an air balloon, the dynamic infrared images of the TSS in the descent process were also obtained by using the thermal infrared imager. The static and dynamic infrared radiation characteristics of the TSS, and the atmospheric transmittance at different wavelengths and slant paths were analyzed. The infrared image sequences can be import into the information processor of the infrared reconnaissance and warning system, which provides the basis for the assessment and evaluation of the action distance, threat alarm and recognition processing of the TSS under various environmental conditions.%针对红外侦查预警系统探测识别末敏弹的关键问题,采用高分辨率红外热像仪研究了一种伞降末敏子弹的红外辐射特性.通过激活末敏子弹的内部热电池,并利用红外热像仪实时监测,得到了末敏子弹的静态红外图像序列;通过在热气球上高空投放末敏子弹,同时利用热像仪实时跟踪捕获的方法,得到了末敏子弹稳定下降过程中的动态红外图像序列.对比分析了末敏子弹的静态、动态红外辐射特性,并对不同波长和斜程下的红外辐射大气透过率进行了理论计算.红外图像序列可注入红外侦察预警系统的信息处理机,从而为考核预警系统对末敏子弹的作用距离、威胁告警及其识别处理等对抗评估技术奠定了重要基础.
