摘要

本文对金属球和介电球的前后向雷达截面(RCS)进行了比较。重点介绍了生成RCS的电动力学背景。结果表明,完全反射目标和能被电磁波穿透的介电目标的散射会产生不同的现象。所得结论有助于更好地理解利用前向散射效应的双基地无源雷达的工作条件。

Electrodynamic study of forward- and backward-scattering from spherical targets
In this paper, a comparison between backward and forward radar cross-section (RCS) profiles of metallic and dielectric spheres is presented. The emphasis is put on the electrodynamic background of generated RCS. It is shown that different phenomena are associated with the scattering from a perfectly reflecting target and dielectric one that can be well penetrated by the electromagnetic wave. Derived conclusions can be useful in better understanding of the operating conditions of bistatic passive radars utilizing the forward-scattering effect.
