摘　　要：红外烟幕是红外成像跟踪系统的一种重要的对抗手段,它对舰船目标遮蔽程度的强弱直接影响跟踪系统的作战性能。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。与对比度评估方法和相关度评估方法的比较实验表明,基于分形拟合误差的评估方法能够更好地反映红外烟幕对舰船目标的遮蔽程度,是一种有效的评估方法。Infrared smoke screen is an important countermeasure against infrared imaging tracker. The extent of infrared smoke screen shielding on ship target affects directly on the tracker＇s performance. The evaluation method of infrared smoke screen shielding on ship target using fractal fitting error is analyzed,and the ε-blanket method of calculating image fractal dimension is improved. The experiment shows that compared with contrast evaluation method and correlation evaluation method ,the proposed method can reflect the extent of infrared smoke screen shielding on ship target better,and is an effect evaluation method.
