日盲紫外探测系统的设计

Design of Solar Blind Ultraviolet Detection System

导弹尾焰是日盲紫外探测的目标,日盲辐射主要来源于燃料在二次燃烧过程中的化学发光和粒子的热辐射。基于点光源推导尾焰辐射强度与系统输出电压的关系,分析系统各个参数的影响。设计探测电路在不同距离对目标进行探测,实验结果表明,系统能够良好响应目标距离的变化。

The solar-blind ultraviolet detection system detects missile plume.Solar-blind ultraviolet radiation comes from the secondary combustion and particles thermal emissions.The relationship between the radiation intensity of missile plume and the output voltage of detection system is established based on the point source radiating.The effects of system parameters are analyzed according to the relationship established.A detection circuit is designed to detect the target at different distances.The result of experiment shows that the system can detect target at different distances.
