Application research for conventional projectiles detect ing and tracking using infrared focal plane array sensor

文中探讨了利用红外跟踪测量技术对常规快速弹丸目标的跟踪与测量。对靶场试验中常用弹丸目标的光谱辐射特性、背景辐射特性以及大气透过率进行了综合分析 ,结合试验结果 ,指出响应工作波段为 3～ 5 μm的红外器件最适于作该类目标的成像探测器。在此基础上计算了利用3～ 5 μm红外焦平面探测器对 12 2mm火箭弹进行探测的作用距离 ,以及红外两站交汇测量系统对12 2mm火箭弹的交汇测量精度。

In this paper, radiation characteristics of target /b ackground and atmospheric transmittance are analysed. By analysing the result of the test, infrared focal plane array sensor working within 3～5μm wave band is considered to be appropriate for detecting and tracking conventional fast movin g object. Based on this, the detecting distance for 122mm rocket using infrared focal plane array sensor within 3～5μm wave band and the precision of two infra red measuring system intersecting measurement are discussed.
