| 摘 要： | 本文从单个探测器的几何分辨率出发,并考虑到大气传输损失对系统信噪比的影响,提出了热成象系统对面目标的极限作用距离的近似解,并对目标和背景的幅射亮度的计算方法进行了详尽的讨论。最后,作为一个例子,计算了某一实际热成象系统的极限作用距离。

| Abstract: | Starting from the point of view of geometrical resolution of simple detector,considering the influence of atmosphere tra-nsmission loss on signal-noise rate of system,this paper presents an app-roximate solution of ultimate operating range in a thermal imaging sy-stem for extended target.The calculation method of radiance of targetand background is discussed in more detail. At last, the ultimate op-erating range of a practical thermal imaging system, is Calculated asan example. |
