| 摘 要： | 针对目前红外热像仪现场性能检测手段的不足,设计一套便携式红外热像仪最小可分辨温差(MRTD)检测装置,首先现场测量出红外热像仪的MRTD,再由大气透过率模型计算得到目标的表观温差,最后通过Johnson准则分析计算得到红外热像仪探测或识别目标的能力.试验结果表明该方法准确可行,可用于各类红外热像仪作用距离的检测.

| Abstract: | Pointing to the deficiency of the in-situ test measurement of the thermal infrared imager,a set of portable test device of the thermal infrared imager with MRTD has been designed.First,test the MRTD of the thermal infrared imager in-situ.And then,calculate the apparent temperature difference of the target through the model of the atmosphere trasmissivity.At last,through the Johnson criterion,analyze,calculate and obtain the ability of detecting and recognizing the target by the thermal infrared imager.The experiment result shows that the method is exactly feasible and may be used to test the findable distance of all rinds of the thermal infrared imager. |
