Abstract

Studies were made of the scattering of electromagnetic waves from nonspherical targets by making exact determination of the nose-on radar back-scattering cross sections of conducting prolate spheroids of various sizes and shapes. Curves are given for the back-scattered cross sections as a function of dimensionless size and shape parameters for prolate spheroids. The results are compared with the Rayleigh-Gans first order approximation and Stevenson's third-order approximation, and the range of applicability of these approximations is evaluated.

非球面目标雷达后向散射截面
通过精确测定不同尺寸和形状的导电长条形球体在雷达前端的后向散射截面,研究了非球形目标对电磁波的散射。给出了长条形球体的背散射截面随尺寸和形状参数的变化曲线。将所得结果与Rayleigh-Gans一阶近似和Stevenson三阶近似进行了比较,并对这些近似的适用范围进行了评价。
