| 摘 要： | 本文采用复射线技术的原理和方法,通过场的高斯波束拟合,使这种理论能够用于进气道之类的大口径凹形腔体的雷达截面(RCS)特性分析。本文以弯曲的蛇形进气道为例,进行了RCS特性分析计算,并将计算值与测试值比较。结果表明,这种方法是一种比较准确而又十分有效的RCS预估方法。

| Abstract: | The elementary principle and method of complex ray have been used for RCS analysis of a large aperture concave hollow target, such as an engine intake by wave expansion with a set of Gaussian beams. In this paper, a curved hollow duct as a model of an engine intake is calculated. The effectiveness and accuracy of the method can be proved from the comparison of the calculation with the measured results. |
