摘要
为满足多波段兼容伪装的需求,采用多种材料合理匹配与多功能层组合结构的方法,制备了一种可实现可见光、红外和雷达多波段兼容的新型复合植被伪装材料。用雷达波屏蔽效能和反射率测试实验对伪装材料的吸波性能进行了测试,用成像法对伪装材料的可见光和热红外伪装性能进行了试验检测。结果表明,研制的伪装材料有良好的雷达波衰减性能,大于5 dB的吸收频宽高达3.9 GHz。植被伪装材料面层纹理、颜色、亮度、热图与背景较为接近,隔热效果明显,具有良好的可见光和红外伪装效果。
To meet the requirements of multiband compatible camouflage,a new composite vegetation camouflage material that can realize multiband compatibility of visible light,infrared,and radar was fabricated by reasonably matching various materials and a multi-functional layer structure.The absorbing properties of the camouflage material were evaluated by a radar wave shielding effectiveness and reflectivity test.The visible and thermal infrared camouflage properties of the camouflage material were tested by an imaging method.The results show that the camouflage material has good radar wave attenuation performance,and the absorption bandwidth at values of 5dB or more is as high as 3.9GHz.The texture,color,brightness,and thermal map of the surface layer of the vegetation camouflage material are close to the background values,and the thermal insulation effect is evident,enabling good visible and infrared camouflage effects.
