Abstract | 随着频率使用率的提高,瞬态信号对射电天文观测影响越来越大,有效的电波环境测量及频谱分析可为现有射电天文台址干扰缓解策略提供依据.基于现有射电望远镜台站电波环境特征,结合信号分析仪原理,深入分析了仪器设备关键参数配置方法及测量时间计算方法;结合实际测量需求,确定了测试时间规划策略,提出一种准实时电波环境测量方法.运用此方法对新疆天文台南山台站电波环境进行测量,分析了频谱、频率占用度随时间变化特点,结果表明,该方法能够有效分析电磁干扰随时间的变化趋势. |
Other Abstract | With the increase of frequency utilization rate, transient signals have a great impact on radio astronomy observations. Effective radio environment measurement and spectrum analysis provide the basis for interference mitigation strategies. Based on the characteristics of radio environment and the principle of spectrum analyzer, key parameter configuration and measurement time calculation methods of the analyzer were analyzed. Then test time planning strategy was determined with measuring requirements, and a quasi-real-time measurement method for radio wave environment was proposed. The method was applied to NSRT (the Nan Shan 25mradio telescope) site, and the variation of spectrum and frequency occupancy with time was analyzed the results show that this method can effectively analyze electromagnetic interference varied with time. |
