摘要

To assist the unceasingly development and application of ultraviolet ( UV) detection system , especially in space military, firstly the major technical performance of the system is put forward and the technical features of the UV optical system and the current technologies of vacuum and solid UV detectors are analyzed based on expounding the composition of UV detection system and working principle. Secondly, it studies the UV characteristics of the target in the perspective of the time, the movement and the radiation characteristic and further induces factors of UV propagation in atmosphere. Moreover, it discusses the dim target signal processing and detection method, which borrows ideas from methods of dealing with the infrared characteristics of the target. Finally, some key technical problems that UV detection system development needs to be settled are suggested. This research has some theoretical guiding effect to the further research and development of the UV target detection system.%为了有助于紫外探测系统的不断发展和应用,尤其是在空间军事上的广泛应用.首先,在阐述紫外探测系统组成与工作原理的基础上,提出系统的主要技术性能,分析紫外光学系统的技术特点,以及真空型和固体型2类紫外探测器的技术现状.其次,从目标的时间特性、运动特性和辐射特性角度研究空间紫外目标特性,并进一步归纳紫外大气传输影响因素.再次,借鉴红外目标信号处理方法,探讨紫外弱目标信号处理与检测方法.最后,指出紫外探测系统发展需要解决的若干关键技术.对于紫外目标探测系统技术的发展与深入研究,具有一定的理论指导作用.
