摘要
背景环境与军用目标复合电磁散射特性的研究,对雷达探测、目标识别、反隐身技术等众多领域的工程应用均有较重要的军事意义。提出了一种基于矩阵低秩类快速算法的混合位积分方程方法,用来快速分析掩体下方军用目标的复合电磁散射特性。该方法由传统矩量法结合自适应交叉近似算法构成,可以实现对藏于防空洞中或掩体下方坦克目标的复合电磁散射特性的快速分析。
The research of composite electromagnetic scattering characteristics from background environment and hard target, has important significance for the radar detection, target recognition, anti- stealth technology, and many other fields of engineering applications. A kind of mixed potential integral equation （MPIE） method, which based on the matrix low-rank fast algorithm, for the fast analysis of the composite electromagnetic scattering of hard target is proposed. The method of moment （MoM） is combined with the adaptive cross approximation algorithm （ACA） to form the new method, which can analyze the elec- tromagnetic scattering from the tank target under the bunker efficiently.
