摘　　要：常规的数字电视干扰信号检测方法以干扰信号外源识别为主,检测到的信号存在一定的误差,影响数字电视的正常使用。因此,设计了卫星数字电视电子干扰信号自适应检测方法。识别卫星数字电视电子干扰信号源,判断数字电视的干扰类别,在载波被锁定的状态下,对干扰信号进行综合检测。检测数字电视欺骗干扰主特征自适应频域,将实际信号接收过程中的特征值分布因素进行分析,根据主特征值波动频域,反映干扰信号的位置。使用对比实验,验证了该方法的检测精准度更高,能够应用于实际生活中。Conventional methods for detecting interference signals in digital television mainly focus on identifying external sources of interference signals,and the detected signals have certain errors that affect the normal use of digital television.Therefore,an adaptive detection method for electronic interference signals in satellite digital television has been designed.Identify the electronic interference signal source of satellite digital TV,determine the interference category of digital TV,and comprehensively detect the interference signal when the carrier is locked.Detect the main feature adaptive frequency domain of digital television deception interference,analyze the distribution factors of feature values during the actual signal reception process,and reflect the position of the interference signal based on the fluctuation frequency domain of the main feature values.Through comparative experiments,it was verified that the detection accuracy of this method is higher and can be applied in practical life.
