针对当前中波红外光电干扰研究中无等比例远距离实验验证的问题，以峰值功率为10 W波长为5.4μm的中波红外激光器对某型中波红外相机进行了距离为15 km的光电干扰实验。实验中选择不同条件进行了多组实验，得到了各条件下的激光干扰图像。通过对图像的分析发现发散角为15 mrad的中波激光器在15 km的距离上对焦距为384 mm的中波红外相机系统在能见度为0.452的中等气象条件下进行干扰时，当输出功率为5.6 W时可使相机无法成像，无法提取目标，此时的功率密度为0.064 mW/m2。实验验证了以当前国内的成熟技术完全可以实现对导弹导引头在15 km以上的中波红外激光干扰。实验数据可以为后续的精确大气透过率模型及中波红外光电对抗损伤评估模型研究中参数的反演与确定提供支持。

An optic-electronic disturbance experiment was don e since there is no same proportion long distance experiment validation in the mid-infrared optic-electronic disturbance research currently. The laser power was 10 W, the wavelength was 5.4μm, the camera of mid-infrared wavelength with the disturbance distance of 15 km was disturbed by the mid-infrared laser in this experiment. Many group experiments were done under some different conditions. A lot of laser disturbance image under the conditions were gained. The laser power density could be calculated using the data. The camera would not distill aim when the laser power being 5.6 W from these images, in this condition the radiation angle of the laser was 15 mrad, the distance between the laser and camera was 15 km, the focus of the mid-infrared camera was 384 mm, the visibility was 0.452 and the power density was 0.064 mW/m2. This experiment can validate the 15 km long distance mid-infrared laser disturbance to missile camera system being coming true using now domestic mature technology. These experiment data can sustain the adding research about the parameter in reversing deducing and confirm in exactitude atmosphere permeation rate mode and mid-infrared optic-electronic confrontation evaluation mode.
