液体泡沫对激光的伪装性能分析

为了研究液体泡沫的激光伪装应用，实验分析了液体泡沫对1.06 m激光的伪装性能。采用对比试验方法测得了不同液体泡沫结构参数下的1.06 m激光回波衰减值，结果显示，衰减值最高可达66%，最低为36%。结合激光伪装要求，以草地和钢板为例，理论计算分析了液体泡沫用来实现1.06 m激光伪装可行性。结果表明，使用2 cm厚液体泡沫对钢板进行伪装，激光回波衰减达到36%，在草地背景伪装要求的30%~40%范围内。说明液体泡沫具有较好的1.06 m激光伪装性能，利用液体泡沫可实现激光伪装和地面目标有效防护。

Experimental study on foam-s camouflage performance

In order to study the application of liquid foam to realize laser camouflage, the experimental camouflage performance of liquid foam on the 1.06 μm laser was discussed. The 1.06 μm laser echo attenuation values were tested measured under the different parameters of liquid foam. The results show that the attenuation value is up to 66% and down to 36%. Then, the application feasibility of foam on laser camouflage was analyzed with the case of grass and steel combined with the laser camouflage requirements. The results show that the attenuation value reaches 36% while steel camouflaging using 2 cm liquid foam, and the value is in the requested range from 30% to 40% of the grass camouflage. So the liquid foam has fine performance in 1.06 μm laser camouflage, and it can realize laser camouflage of ground targets using liquid foam.
