SBR 雷达散射截面快速算法在雷达隐身设计中的应用

摘要

目前RCS预估方法大致可以分为两大类：精确方法和近似方法。而近似方法运算速度快，适合在工程实际中应用，但准确度相对较低。选取了弹跳射线（SBR）法，既具有运算速度快的特点，又具有较高的准确度。简要论述了其原理以及应用情况，通过典型算例验证了其方法仿真的准确度，并介绍了某型雷达外形隐身设计案例。%Existing pre‐estimation methods of radar cross section (RCS ) can be classified to two kinds :precision method and approximation method .The approximation method has high calculation velocity ,is adapted to the application to engineering practice ,but the precision is low .T his paper u‐ses the method of shooting and bouncing ray (SBR) that has not only fast calculation velocity but also high precision ,briefly discusses the principle and application status ,validates the simulation precision through classical calculation example ,and introduces the shape stealth design case of a certain radar .
