摘　　要：为了有效发挥泡沫遮障层对激光的遮蔽能力,利用了激光在传输路径上散射和反射的相关理论,计算分析并实验验证了施放泡沫遮障层前后目标表面光斑尺寸大小与探测器接收到的来自目标表面激光功率以及与泡沫遮障层干扰效果之间的关系。研究表明,当激光光斑尺寸较大时,激光束能量较分散,泡沫遮障层对激光束的干扰效果较好。Using the scattering and reflection theory in the passing route of laser, the relationship among the dimension of the laser spot, the received laser power of the detector from the target, and the interference effect is obtained before discharging the foam screen and after that through deduction and calculation of relative theory. From the results of calculation and analysis, it shows that the bigger dimension of laser spot and the less focused, the better interference effect will be.
