摘要
Abstract
[Background]Slots are critical weak scattering sources in stealth aircraft design,significantly influencing Radar Cross Section(RCS).Existing simulation and measurement models often fail to capture true weak scattering behavior,as it is difficult to isolate slot scattering from the low-RCS background.[Purpose]This study aims to accurately quantify the RCS contribution of weak slots by separating their scattering effect from the background structure,establishing relationships between slot dimensions and RCS,and developing a fast estimation method for various slot configurations.[Methods]Using the electric field vector superposition principle,a cancellation technique was applied to extract slot scattering from the background.A fast multi-target scatterer accumulation method was developed to predict scattering from single straight slots,arrays,and bent slots.Simulations and experiments were conducted for validation.[Results]The cancellation technique effectively isolated slot scattering,revealing clear RCS—dimension correlations.The fast estimation method agreed well with detailed simulations and experimental measurements across different slot types.[Conclusions]The proposed approach offers an effective tool for designing and optimizing aircraft structures such as skin joints and apertures.It enables efficient RCS evaluation of weak scattering sources,enhancing stealth performance assessment capability.关键词
