摘　　要：降低弱散射源的雷达散射截面,增强飞行器部件的隐身性能至关重要。但部件脱离飞行器后,需依托载体才能得到准确的隐身性能。通过探究低散射载体设计机理和思路,考虑爬行波、行波、入射频率等影响因素,设计了一款低散射载体。通过理论建模、特征基函数法仿真计算和试验测试方法验证,所设计的低散射载体的雷达散射截面足够低,可有效消除弱散射源以外的其他杂波散射影响,还原部件真实状态,有利于提升弱散射源隐身性能评估的准确性,从而优化飞行器隐身设计。It is important to reduce the radar cross section(RCS)of weak scattering sources and enhance the stealth performance of aircraft components.However,after the component is separated from the aircraft,it needs to rely on the carrier to obtain accurate stealth performance.By exploring the design mechanism and ideas of low-scatter carrier,considering crawling wave,traveling wave,incident frequency and other influencing factors,a low-scatter carrier is designed.Through theoretical modeling,characteristic basis function method simulation calculation and test method verification,the results show that the RCS of the designed low scattering carrier is low enough,which can effectively eliminate the influence of clutter scattering other than weak scattering sources,restore the true state of the components,and help improve the accuracy of stealth performance evaluation of weak scattering sources,thereby optimizing the stealth design of the aircraft.
