| 摘 要： | 在排气引射红外抑制系统的实验研究中, 通过对目标背景的各种处理方法、实验对比及分析, 了解背景对目标红外辐射特性测量的影响规律。实验结果表明:在大背景小目标情况下, 必须十分注意对背景进行遮挡和冷却处理。在选择遮挡材料时, 如果被遮挡部位处于高温部件的直接辐射场中, 则应选用表面发射率高的板材, 否则应选用高反射板材。遮挡板的定向应使其板面垂线与探测器轴线有较大夹角。

| Abstract: | The effects of background on target infrared radiation measurements were investigated experimentally by means of background treatment and under different meteorological conditions.Some suggestions are offerred for eliminating the effects of the background and improving the infrared radiation measurement of the target,as well as for recording meteorological conditions to correct the infrared radiation measurements. |
