Abstract

This article presents an accurate and efficient method for determining the locations of scattering centers on a complex 3D scatterer. For a given excitation, a localized integration technique is used to calculate the contribution of each surface mesh element to the scattered field in the specified direction. The contribution of a point is computed exclusively by utilizing the currents induced on the surface of the scatterer. The effect of a given point situated on the surface of the scatterer is quantified by the radiation of the current elements within a predefined volume around that point. The algorithm is efficiently implemented with the aid of parallel computing. Numerical experiments involving radar cross-section reduction (RCSR) and antenna siting on a large platform are performed. The suggested approach demonstrates a superior performance compared to traditional methods, such as 1D range profiling, in terms of both efficiency and accuracy for extracting scattering centers.

通过诱导表面电流探测复杂散射体的散射中心 [Em 程序员笔记本］

本文介绍了一种精确而高效的方法，用于确定复杂三维散射体上散射中心的位置。对于给定的激励，采用局部积分技术计算每个表面网格元素对指定方向散射场的贡献。点的贡献完全通过利用散射体表面上的感应电流来计算。位于散射体表面的给定点的影响通过该点周围预定体积内的电流元素辐射进行量化。该算法借助并行计算有效实现。在一个大型平台上进行了涉及雷达截面缩小（RCSR）和天线选址的数值实验。与传统方法（如一维范围剖面法）相比，所建议的方法在提取散射中心的效率和准确性方面都表现出更优越的性能。

期刊介绍： IEEE Antennas and Propagation Magazine actively solicits feature articles that describe engineering activities taking place in industry, government, and universities. All feature articles are subject to peer review. Emphasis is placed on providing the reader with a general understanding of either a particular subject or of the technical challenges being addressed by various organizations, as well as their capabilities to cope with these challenges. Articles presenting new results, review, tutorial, and historical articles are welcome, as are articles describing examples of good engineering. The technical field of interest of the Magazine is the same as the IEEE Antennas and Propagation Society, and includes the following: antennas, including analysis, design, development, measurement, and testing; radiation, propagation, and the interaction of electromagnetic waves with discrete and continuous media; and applications and systems pertinent to antennas, propagation, and sensing, such as applied optics, millimeter- and sub-millimeter-wave techniques, antenna signal processing and control, radio astronomy, and propagation and radiation aspects of terrestrial and space-based communication, including wireless, mobile, satellite, and telecommunications.
