摘要
除了干扰激光功率,合作目标温度也是影响定向干扰效果的重要因素之一。本文开展了中波激光对中波红外成像制导系统的干扰实验,获取了不同干扰强度下红外导引头对不同温度合作目标的跟踪情况,分析研究了合作目标温度、干扰激光功率等对红外定向干扰效果的影响。结果表明,导引头所攻击目标温度影响对导引头的红外定向干扰效果,合作目标温度越高,其中波红外辐射强度越高,需要的干扰激光强度越高,即需要更高的干扰压制比,才能达到一致的干扰效果;另外,目标温度影响导引头对图像灰度分割门限的计算,从而影响干扰激光对导引头图像的饱和与串扰现象,最终影响对目标的提取和跟踪。
The cooperative target temperature is one of the important factors that affect the direction jamming effect.The jamming experiment of mid-infrared laser to IR imaging guiding system was carried out,and the object extraction and tracking in different jamming laser intensities and different target temperatures are obtained.Based on the experiment data,the impact of target temperature and jamming laser intensity on IR direction jamming effect was investigated and analyzed.The results show the jamming effect depends on the temperature of target.When the target temperature is higher,the mid-infrared radiation is stronger and the needed jamming laser intensity is higher.Because the IR radiation intensity of target affects the image segmentation threshold and the saturation and crosstalk of guidance image,it will affect extraction and tracking of the object.
