Abstract

In order to study the effect of laser backscatter on the laser semi-active seeker, establish a laser backscatter model to analyze the influence of laser backscattering and calculate how much the safety distance(vertical distance between seeker and laser beam) is required correspondingly. Change the angle of view of the seeker, to analyze the influence of backscatter under different field angles. It was found that the larger the field angle is, the stronger the effect of laser backscattering is. By changing the visibility of the atmosphere and analyzing the effects of backscatter on the seeker under different conditions of atmospheric visibility, it was found that the smaller the atmospheric visibility, the stronger the laser backscattering effect. In short, by changing the angle of view of the seeker and atmospheric visibility, the effect of the backscattering phenomenon can be changed and it requires different safety distances to guarantee the safe launch of missiles correspondingly.
