中文摘要： 电磁测量数据处理理论和方法是近场测量中最为核心的关键技术，传统数据处理方法因无法实现对空间不同位置散射源的贡献分离而在高精度辐射和散射测量方面面临很大困难.本项目将基于数学反射抑制理论研究对应的测量数据处理方法。项目首先依据数学反射抑制理论揭示近场测量中如何对不同空间位置散射源的散射场进行数据分离的基本原理;然后以此为基础结合近场辐射和散射测量实际需求，在近场测量的干扰抑制、探头互耦抑制、大型阵列诊断、目标成像等方面进行深入研究,形成新的数据处理理论体系和具体的数据处理方法。该方法可用于对现有测试系统测量精度的提升，进一步发展甚至可形成非暗室环境测试系统，实现对大型阵列天线在载体上的原位高精度测试和诊断。

英文摘要： Electromagnetic measurement data processing theory and methods are the most significant technology in near-field measurements. The traditional method of data processing faces great difficulties in high-precision measurements of radiation and scattering due to the separated contribution of scattering source in different spatial location. This project will research the corresponding measurement method of data processing based on mathematics reflection inhibition theory. First, based on the theory of mathematical reflex inhibit, the project reveals the basic principles of data separation of the scattered field when the scattering source located in different spatial position in near-field measurements; then on this basis ,combining with actual demand of near-field radiation and scattering measurement, an in-depth study is done of interference suppression in the near-field measurements , suppression of mutual coupling probe, a large array of diagnostic, target imaging, etc. and form a new system of data processing theory and specific data processing methods. This method can be used to enhance the measurement accuracy of the existing test systems, further developed, it can even form a non-darkroom environment testing system, achieving high-precision testing and diagnosis in situ to large array antenna on the carrier.
