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.
