随着物联网和通信技术的迅速发展,频率资源供需矛盾日益突出.为了对电磁环境进行测试和数据采集,掌握各种无线电业务和通信系统,特别是宽带无线接入、物联网等新业务用频的背景噪声和频率使用情况,设计了一种超短波频谱监测网络化接收机.该接收机监测的频率范围为20 MHz～3 GHz,可提供多种IF处理带宽以适应处理不同信号的要求,具有较高的接收灵敏度和抗干扰性能,并具有最佳信噪比,能适应较宽动态范围的监测需要.%With the rapid development of IOT and communication technology, the contradiction between supply and demand of the frequency resources has become increasingly prominent. An ultrashort wave spectrum monitoring network receiver was designed for testing and data acquisition of the electromagnetic environment to master all kinds of wireless business and communication systemi especially the broadband wireless access, IOT and other new business with frequency of background noise. The frequency range monitored by the receiver is from 20 MHz to 3 GHz. The receiver can provide a variety of IF processing bandwidth to adapt to the requirements of the different signals, with high receiving sensitivity and antijamming performance, has the best signal to noise ratio, and can adapt to the demand of a wide dynamic range monitoring.
