摘要
基于非平衡磁控溅射技术在浮法玻璃表面沉积了系列掺铝氧化锌(AZO)和氧化铟锡(ITO)薄膜,从电磁隐身角度出发,确定了两种薄膜的电磁散射测试方法和分析方法,并测试了10、15 GHz的HH、VV的极化雷达散射截面(RCS)曲线,以试验数据为基础,研究了方块电阻对两种薄膜电磁散射的影响特性。试验结果表明,AZO与ITO散射曲线具有相似性,AZO散射曲线震荡性更明显;两种薄膜RCS增益随着方块电阻的增大而变小,AZO和ITO的RCS增益曲线均震荡性降低;方块电阻合适时,两种薄膜均可实现座舱玻璃隐身。
Herein, we reported the electromagnetic stealth behavior of the Al-doped zinc oxide （AZO） and in- dium tin oxides （ITO） coatings, deposited by unbalanced magnetron sputtering on glass substrate. The influence of the sheet resistance and transmittance on the electromagnetic scattering of the AZO/ITO coatings was theoretically analyzed and experimentally evaluated by measuring the Radar Cross-Section （CRS） ,irradiated at 10 GHz/15 GHz and polarized in Horizontal-Horizontal （HH）/Vertical-Vertical （VV） modes. The results show that the sheet re- sistance strongly affected the RCS curves with similar structures of the AZO/ITO coatings. For example, as the sheet resistance increased, their RCS gains oscillatingly decreased, with that of AZO film oscillating more obviously. We suggest that the AZO and ITO coatings with the optimized sheet resistance may do an excellent job for cockpit glass stealth.
