    摘要:

    考虑到大气环境条件、红外探测器的性能以及目标和背景热辐射特征等因素对红外成像跟踪系统作用距离的影响,针对红外成像跟踪系统作用距离的指标要求,在保证目标成像像素大小和目标与背景图像反差不变的情况下,提出了通过近距离小目标小温差等效替代的作用距离测试方法,并对等效测试的结果进行了远场动态试验验证,所得结果为红外成像跟踪系统的设计和作用距离评估提供了依据。

    Abstract:

    Considering the influence of the atmospheric conditions,the performance of infrared detector and thermal radiation characteristics of the targets and backgrounds on the operating distance of infrared imaging and tracking system,based on the specific qualification request of the operating distance of infrared imaging and tracking system,an equivalent testing method of the operating distance is presented when the pixel size of target image and the contrast of the target and the background is fixed. This method has the characteristics of close distance,small target and small difference of temperature. Equivalent results are verified by dynamic testing of far field,which provide a fundamental basis for the design and operating distance evaluation of infrared imaging and tracking system.
