【摘要】 座舱玻璃镀膜是实现飞行器隐身技术的重要途径之一。利用雷达散射截面(RCS)均值增益研究铌掺杂ITO镀膜玻璃隐身性能;针对不同方块电阻的铌掺杂ITO镀膜玻璃,进行系列化RCS暗室测试,分析不同入射频率、极化方式的电磁散射特性。结果表明:方块电阻增大时电磁散射减弱,合适的方块电阻(小于40Ω/m~2)有利于实现座舱外形隐身,散射特性与金属接近,频率较高时,镜面散射波峰较窄。更多还原

【Abstract】 The coating for cockpit glass is one of the important ways to realize aircraft stealth technology.The stealth characteristics of Nb-doped ITO(Indium Tin Oxides)coated glass is studied by using the RCS(Radar Cross Section)mean gain.A series of RCS darkroom tests are carried out for Nb-doped ITO coated glasses with different sheet resistance,and the electromagnetic scattering characteristics with different incident frequencies and polarization modes are analyzed.It is found that,when the sheet resistance increases,the electromagnetic scattering decreases,and the appropriate sheet resistance(less than 40Ω/m~2)is beneficial to realize the shapestealth of cockpit,and its scattering characteristic is also close to the metal’s,the peak of specular scattering is narrow when the frequency is high.更多还原
