多频谱红外烟幕干扰弹的反制方法

介绍了多频谱红外烟幕干扰弹的反制条件和反制时机;在可反制的阈值范围内,对烟幕遮蔽下的目标进行图像增强等预处理后,采用小波多分辨分析和分形布朗随机场模型,计算分形维数和分形拟合误差,从而判断目标所在区域;最后采用最佳熵自动阈值法确定分割门限,将目标从烟幕遮蔽中分割出来.实验证明,该方法效果明显,是对多频谱红外烟幕干扰弹反制最为关键的一步.

Countermeasures of the Multispectral Infrared Interference Bullet

This paper introduces the condition of countermeasures of the multispectral infrared interference bullet.It uses the image enhancement in the threshold of the resisted scope.In order to judge the region of the objective place,this paper uses the wavelet transform and fractal theory to compute the fractal dimensions and the fitting errors.Then it uses best entropy that computes the numerical value of threshold to divide the target from the infrared image.The experiment proves that the means of this paper have good effects,and it is the critical step for the countermeasures of the multispectral infrared interference bullet.
