【摘要】 本文根据复射线分析和场的高斯波束展开,提出了一种计算复杂目标电磁散射特性的简便方法。由于复射线法不受目标形状的限制,因此该方法可用于任意形状的目标。本文以矩形进气道为例,进行了雷达截面分析计算,并将计算值与测试值比较,结果表明这种方法是可行的。更多还原

【Abstract】 Based on the complex ray method and source expansion with a set of Gaussian beams, a new method for analysis and calculation of radar cross-section (RCS) of a complex target is presented. This method can be used for arbitrary shaped object, because complex ray analysis is not limited by the shape of object. A hollow rectangular pipe as a model of an air intake is investigated. The effectivenejs of this method can be proved from the comparison of calculated and measured results.更多还原
