摘要 数字卫星电视的信道具有开放性,易受自然环境干扰和人为破坏,影响播出安全。文章详细阐释了数字卫星电视原理以及主要监测技术,总结了常见干扰类型特征,为准确定位干扰源精准监测提供了参考。 The channel of digital satellite TV is open,so it is vulnerable to natural environment interference and man-made damage,which affects the broadcast safety.This article explains in detail the principle of digital satellite TV and the main monitoring technology,summarizes the characteristics of common interference types,and provides a reference for accurate positioning and accurate monitoring of interference sources.
