摘要
为提升地面装备目标伪装防护作战效能,仿真设计了一种泡沫夹心结构超宽带电阻型吸波超材料,材料总厚度为21 mm,吸波性能在1~40 GHz范围内小于-10 dB。采用丝网印刷工艺和真空袋压工艺,制备了相应的超宽带吸波超材料,面密度仅为4 kg/m^(2),应用于武器装备隐身防护后,雷达散射截面(RCS)平均减缩10 dB。研究表明该吸波材料具有面密度小、吸波频段宽的特点,有望提升装备隐身性能。
In order to improve the combat effectiveness of camouflage protection of ground equipments,a foam sandwich structure ultra-wide-band resistive wave absorbing metamaterial is simulated and designed,which has a total thickness of 21 mm,and the wave absorbing performance of less than-10 dB within the range of 1~40 GHz.Then,corresponding ultra-wide band wave absorbing metamaterial was prepared using screen printing technology and vacuum bag pressing technique,its surface density is only 4 kg/m^(2).After being applied to the stealth protection of weapons and equipments,the radar cross section(RCS)decreased by 10 dB on average,indicating that the absorbing material has the advantages of small surface density and wide wavelength absorbing band,which is expected to improve the stealth performance of ground equipments.
