卫星电视干扰器原理和现状研究

Study on the Theory and Present Situation of Satellite TV Jammer

近年来,工业和信息化部和省无线电管理部门均出台相关文件和法规,明确要求禁止任何单位和个人非法研制、生产、销售和使用卫星电视无线电干扰器,但因利益驱使,卫星电视干扰器的销售和使用不但屡禁不止,反而迅速蔓延。卫星电视干扰器不仅干扰卫星电视信号,对国防通信和正常民用无线电通信也存在潜在威胁,极大地扰乱了电波秩序。本文分析了近年卫星电视干扰器的使用情况,并对其原理和特性进行了研究。

Recent years,relevant documents and regulationswere published by the Ministry of Industry and Information Technology and the provincial radio management departments,which explicitly ban on any illegal units or individuals to develop,manufacture,sale and use the satellite TV jammers.However,driven by the benefits,sale and use of the satellite TV jammers spread rapidly,instead of reducing.The Satellite TV jammers interfere with the satellite TV signals,as well as the civiland country defense communications,which greatly disrupted the order of radio waves.Thispaper analyzes the present situation of theSatellite TV jammers,and studies on its interferingtheory and characteristics.
