激光光斑尺寸对烟幕干扰效果影响的研究

为了提高激光武器抗烟幕干扰的能力，通过利用相关理论进行推导和计算，分别得出施放烟幕前后目标表面光斑尺寸的大小与探测器接收到的来自目标的激光功率以及烟幕干扰效果之间的关系，以模拟烟幕对激光武器的干扰效果评估。验证了理论推导和计算基本符合实际情况。研究表明，光束的半径越小，能量越集中，烟幕对激光武器的干扰效果越差，激光武器的抗干扰能力越强。

Effect of smoke screen interference on the dimension of the laser spot

The effect of smoke screen interference on by the dimension of laser spot on the surface of the target is studied. To enhance the anti-jamming ability of the laser weapon, the relationship among the dimension of the laser spot, the received laser power of the detector from the target,and interference effect is obtained before discharging the smoke screen and after that through deduction and calculation of relative theory.By this way, the interference effect of smoke screen is simulated. At last, the conclusion is proved by experiment. It is found that if the dimension of laser spot is smaller, the power is more focused, the interference effect is worse, and the anti-jamming ability is better.
