摘    要:卫星电视信号传输网络是国家重要的基础网络,由于其公用性、开放性等特点,广播电视节目信号在传输过程中容易受到干扰。近年来随着科学技术的快速发展,空中各类电波增多且发射功率越来越大,干扰信号的种类和干扰方式不断增多,对卫星电视信号的正常传输影响越来越大。本文简要介绍了干扰信号的分类、产生根源及基本排除方法。信号稳定时生成模板,根据卫星信号受干扰时引起的载波变化,当信号受干扰时利用软件准确预警。

关 键 词:卫星电视  干扰  预警

Abstract:The satellite TV signal transmission network is an important national infrastructure network, the characteristics of its public, open. Radio and television signals susceptible to interference during transmission. With the rapid development of science and technology in recent years, the air all kinds of waves increased and increasing transmit power, the types of interference signals and interference is increasing, the increasing influence of the normal transmission of satellite television signals. Brief introduction to the classification of interfering signals, the root causes and basic troubleshooting. Stable signal is generated when the template to use software and accurate early warning satellite signal interference caused by the carrier change when signal interference.
Keywords:DTV  interference  interference alarm
