摘　　要：采用炭包EPS颗粒作为吸波材料填充迷彩伪装布,通过将迷彩布分格填充的方式研究颗粒分布状态对伪装布在1.7~18 GHz频段吸波性能的影响。结果表明,低频段内各试样吸波效果较差,而在X波段反射损耗可达到-8 dB,吸波性能有所提高;Ku波段反射损耗达-17^-9 dB,吸波性能大幅提高。这种差异主要是由于入射电磁波与底面反射电磁波发生干涉、增强吸波小球吸收电磁波的结果。Camouflage cloth with microwave absorption function was prepared using carbon package EPS particles as divided absorbing material filling,and the effect of the EPS particles distribution status on microwave absorption performance of the camouflage cloth were researched from 1.7 GHz to 18 GHz.The results show that the microwave reflection loss of each sample in low frequency is poor.In X band,the reflection loss achieves-8 dB,which shows the microwave absorption performance is improved.However,in Ku band,the microwave absorption performance is improved greatly and reach-17^-9 dB.This difference attributec to the microwave interference loss between incident electromagnetic wave,and the excellent microwave absorption performance of the carbon package EPS particles.
