摘　　要：介绍了超短波、微波扩频及卫星技术在数字遥测地震台网中的应用领域及优势 ,根据各频段无线电波的传播特点和数字遥测台及中继站数据复分复接技术要求 ,阐述了无线技术在数字遥测地震观测系统中实现的方式和步骤 ,并叙述了超短波及无线扩频技术在合肥数字遥测地震台网的应用以及在实施过程中需注意的几个技术环节。In this paper, we introduced the applied field in digital telemetric seismic network and the advantage of the ultra-short wave, extending frequency of microwave and communication technology. According to radio disseminating feature of every frequency bands and the technology demand of the transferred data compounded and uncompounded by digital seismic stations and relay stations, we explained the method and the step of the radio technology applied to digital telemetric seismic network and displayed some techniques and key places in the process of applied the ultra-short wave and extending frequency of microwave to Hefei Digital Telemetric Seismic Network.
