摘　　要：中波发射射频信号的接收容易产生高频干扰,影响信号接收效果。文中设计了一种中波发射射频信号接收高频干扰快速消除方法。首先,分析了高频干扰的产生原因,基于电源电路实现中波发射射频信号的采集,采用多相复调制滤波器群方法将信号分离,从中提取出高频干扰信号。其次,设定滤波器实现高频干扰信号消除。最后,通过实验,发现该方法在各种发射频率下均具有较高的干扰消除率,最高可达到95%,且射频信号损耗率较低,平均为0.22%,表明其能快速有效地消除高频干扰,具备较好的性能表现。The reception of medium wave transmitting radio frequency signals is prone to produce high frequency interference,which affects the signal reception effect.A fast elimination method of high frequency interference received by medium wave transmitting radio frequency signals is designed in this paper.First,the causes of high frequency interference are analyzed.The acquisition of medium wave transmitting radio frequency signals is realized based on the power supply circuit,and the signal is separated by the multi-phase complex modulation filter group method,and the high frequency interference signal is extracted from it.Secondly,the filter is set to eliminate the high frequency interference signal.Finally,through experiments,it is found that the method exhibits a high interference cancellation rate at various transmission frequencies,up to 95%,and the RF signal loss rate is low,with an average of 0.22%,indicating that it can quickly and effectively eliminate high-frequency interference and has good performance.
