| 摘 要： | 介绍了紫外告警原理及紫外告警系统的结构组成。基于典型目标(导弹)的紫外辐射特征和紫外辐射的大气传输特性,结合紫外告警系统探测器件的性能参数,根据像平面照度公式,提出了紫外告警系统探测距离的估算方法及模型,实例计算并验证了紫外告警系统在不同观察方位角对固体推进剂导弹的探测距离。分析研究表明,改变CCD最小照度值,像管的增益,光学系统的透过率和相对孔径等探测传感器的性能参数,可以提高紫外告警系统的探测距离。

| Abstract: | Ultraviolet (UV) warning theory and configuration of UV warning system were introduced. The estimating method and model of detectable distance for ultraviolet (UV) warning system were proposed. The method and model are based on the UV radiation performance of typical target (rocket) and atmospheric transmission performance of UV radiation, integrated the performance parameters of UV warning system, applied the formula of image plane irradiance and imaging. The detectable distance of UV warning system for solid propellant rocket at different angles was computed and invalidated by instance. The analysis and conclusion showed that the detectable distance for UV warning system could be increased by changing the performance parameters of detector, such as CCD minimum luminous density, image intensifier's gain, optical system's transmittance and relative aperture. |
