关于科学和准确采集短波频谱数据的研究

Research on Scientific and Accurate Acquisition Shortwave Spectrum Data

在短波频段,如何能够采集到全面有效准确的频谱数据,分析出频谱占用度等无线电管理的基础数据,形成直观的有价值的信息是我们面临的问题。本文从时间域、空间域和频率域等方面研究了影响数据采集准确性的因素,并分析了短波频段背景噪声的特点,研究了在占用度统计分析中根据背景噪声设置动态门限的重要性。

In HF band, how to form valuable information form the radio monitoring is a problem that we have been studying. This requires to collect comprehensive, effective and accurate spectrum data, and use the correct method to analyze the basic data of radio management, such as spectrum occupation and so on. In this paper, the factors which affect the accuracy of data collection are researched from the time domain, space domain and frequency domain, and then the method of setting the dynamic threshold for the statistical analysis of occupancy is studied based on the analysis of the characteristics of the background noise in HF band.
