Design and implementation of a real-time electromagnetic environment monitoring system

With the advancement of digital technology, the influence of transient signals on radio astronomy observation is growing, and it is imperative to conduct real-time electromagnetic environment monitoring technology research and engineering applications that require the measurement of transient signals. First, in this paper, the hardware architecture design scheme of the electromagnetic environment monitoring system is presented based on the actual measurement of the radio astronomy station. Second, a real-time electromagnetic environment monitoring measurement time configuration method is proposed based on the relationship between signal analyzer parameter configuration, measurement time, and measurement uncertainty. The technical methods of data compression, multithread parallel processing, and ring buffer design are adopted to achieve high-data data transmission, thus improving the reliability of the measurement system. Finally, the system measurement software and web-based spectrum monitoring software are developed to allow real-time electromagnetic environment measurement and monitoring. These were applied to QTT (QiTai Radio Telescope) sites and provided data support for analyzing transient signal characteristics and interference mitigation strategies.
