根据我国现有条件下对无线电信号进行监测的需求,文章提出了无线电信号接收系统的一般设计思路,描述了针对ICM-R7000接收机的具体实现方案。所介绍的接收系统由计算机及其支持软件、接口电路、信号采集电路等四部分组成。它在计算机软件支持下,通过人工置入有关参数,能够实现频道的快速自动搜索、信号的自动采集和信息的自动提取等功能。
According to the requirement of radio signal monitoring under current conditions in our country, the article presents the general design idea of radio signal receiving system and describes the specific implementation scheme for ICM-R7000 receiver. The receiving system introduced by the computer and its support software, interface circuits, signal acquisition circuit composed of four parts. With the support of computer software, it can automatically search channels, automatically collect signals and extract information automatically by manually setting related parameters.
