摘要
短波信号的分析和识别是通信侦查和无线电监测管理的一项关键技术。在日常监测中,无法实现信号的在线分析时,需对信号采集存储以进行人工分析。本文对日常监测工作中离线信号音频文件存储中遇到的问题进行了详细的分析,并根据分析结果总结了一些相关的工作经验,并详细说明了将信号存储为音频文件的参数设置方法及记录条件等,为信号的音频文件存储提供有效参考。
The analysis and recognition of the shortwave signal is the key technique of radio management and radio monitoring. In routine monitoring wok, we often need to analyze shortwave signal manually. In order to get the characteristics of the signal correctly, the data of the signals which need to be analyzed must be sampled and recorded properly. The essay gives the detailed explanation to some problems about sampling and recording of signal. Additionally, we summarize some experience in this work.
