摘要
本文对一种隐身轻量化水下航行器桅杆的设计进行了论证。首先，设计波纹形状以减小雷达横截面(RCS)。通过优化波纹形状的角度和深度参数，RCS降低了26 dB。其次，采用一种既能吸收入射波又能承受载荷的结构雷达吸波材料(SRAM)。通过在波纹形状上铺设SRAM，实现了23.7 dB RCS降低。最后，为了减轻重量，用复合材料代替钢材料，可实现47%的减重。
Design of a stealth and lightweight underwater vehicle mast
In this paper, the design of a stealth and lightweight underwater vehicle mast is demonstrated. Firstly, a corrugated shape is designed to reduce the radar cross section (RCS). By optimizing the angle and depth parameter of the corrugated shape, a 26 dB RCS reduction is obtained. Secondly, a type of structural radar absorbing material (SRAM) is used, which can not only absorb incident wave, but also bear loading. By laying SRAM on the corrugated shape, a 23.7 dB RCS reduction is achieved. Finally, in order to reduce weight, the steel material is substituted by composite material, which can achieve 47% weight reduction.
