摘要: 针对复杂电磁环境特性认知与可视化的现实应用需求，设计了一套基于分层认知概念的雷达信号环境测量系统，实现了对外界多个雷达辐射源信号参数的感知测量，同时以二维坐标形式对测量过程中的各种物理量进行了分层可视化展示。该系统的设计实现期望能够为电磁环境感知、分析提供一种有效的技术方案参考。Abstract: Aiming at the practical application requirement of recognizing and visualizing the characteristics of complex electromagnetic environment, a radar signal environment measurement system is designed based on layered cognitive concept. The system realizes the sensing measurement of signal parameters of multiple external radar emitters. At the same time, various physical quantities are visualized in layers along with the measurement process in the form of two-dimensional coordinates. The design and implementation of the system is expected to provide an effective technical reference for electromagnetic environment perception and analysis.
