Countermeasure effect evaluation of smoke screen on infrared imaging tracker

烟幕是红外成像跟踪系统的一种重要的对抗手段,对其干扰效果的评估具有重要的意义。首先研究了基于分形拟合误差的红外烟幕对舰船目标遮蔽效果的评估方法,改进了毯子覆盖法进行分形维计算的实现方法。之后,以典型跟踪算法为例,将分形拟合误差量化,评估了烟幕对红外成像跟踪系统的干扰效果。仿真实验表明,基于分形拟合误差的评估方法能够真实地反映烟幕对红外成像跟踪系统的干扰效果,是一种有效的评估方法。

Infrared smoke screen is an important countermeasure against infrared imaging tracker, and it is necessary to evaluate its countermeasure effect. First, the method based on fractal fitting error for evaluation of infrared smoke screen shielding on ship target is analyzed, and the s-blanket method is improved for calculating image fractal dimension. Then, the countermeasure effect of smoke screen on infrared imaging tracker with typical tracking algorithm is evaluated using the quantization of fractal fitting error. The experiment shows that the proposed method can reflect the countermeasure effect of smoke screen on infrared imaging tracker exactly, and is an effective evaluation method.
