摘　　要：尽管国内外在目标电磁散射特性研究领域取得了很大进展,但是从技术本身来说该专业领域仍然存在一些难点问题.同时,复杂环境下低散射目标的探测与识别等应用,以及太赫兹等新体制雷达的研发对目标电磁散射特性研究提出了新的需求、引入了新的问题.围绕这些应用需求和技术难点,本文从理论建模、散射测量和特征提取三个方面,归纳总结了目标电磁散射特性研究存在的若干热点和难点问题,期望为从事该方面研究的科研人员提供方向性的引导.Although great progress has been made in the research field of target electromagnetic scattering characteristics at home and abroad, there are still some difficult problems for the technology itself. At the same time, the applications, such as for low scattering target detection and recognition in complex environment and new radar system development such as Terahertz radar, put forward a new demand in the research of target electromagnetic scattering characteristics. According to the requirements of these new technologies and applications, this paper summarizes several hot topics and difficult problems from three aspects, scattering modeling, scattering measurement and signature extraction. This paper is expected to provide some directional guidance for researchers in this field.
