掺杂Sm_2O_3/丙烯酸酯涂料的雷达吸波性能研究

Study on Radar Absorbing Performance of Doped Sm_2O_3/Acrylate Coatings

雷达隐身技术是当前世界各国研究的热点问题,而隐身材料性能的好坏是实现雷达隐身技术的关键。用圆形同轴试样波导法测试了氧化钐、碳纳米管及其两者的复合物在1～18GHz的电磁参数,采用弓形法测试了3种涂层的雷达波反射曲线,并验证了其雷达波反射曲线与电磁参数曲线的一致性。

At present, studying on radar stealth technology is a hot spot in the international community. But it is the key factors of carrying out radar stealth technology that the property of stealth material is good or bad. The electromagnetic parameter of samaria, carbon nanotubes and their compound are tested by the waveguide method of round coaxial sample in 1-18GHz. The reflectivity curves of radar wave of three coatings are tested by the arc method. Furthermore it is proved the consistency between the reflectivity curves of radar wave and the curves of electromagnetic parameter by the experiments.
