天幕靶技术研究进展

Advances in Sky Screen Technology

天幕靶是常规靶场常用的测量仪器,因其操作简便、成本低、测试精度高、稳定可靠性好等优点,在测量飞行物体速度、立靶密集度等方面得到广泛应用.文中分析了天幕靶工作机理,总结了近年来科研工作者在解决天幕靶视场小、灵敏度低、时间信息提取误差大等关键问题时所采用的技术和天幕靶技术的应用,展望了今后的发展趋势.

Because of its easy operation,low cost,high precision,great reliability and stability, the sky screen target,a commonly used measuring instrument, has found wide use in measuring the velocity of flying objects and the concentration of targets. The paper starts with the mechanisms of sky screen targets and then introduces technoIogies adopted in recent years by researchers to solve the problems sky screen targets have, such as small field of view, low sensitivity and big error. Finally, the future development of sky screen targets is discussed.
