摘　　要：脉冲干扰作为一种常见的干扰样式,经常影响卫星导航接收设备的正常定位。为能检测及抑制有意或者偶发的脉冲干扰信号,研究了一种简易的脉冲干扰识别及抑制方法,算法对统计时间内的信号进行分段,统计每段信号的最大值及最大值中的最小值,寻找初始门限,进而统计得到自适应的脉冲干扰检测门限,大于门限的采样信号进行置零处理,小于门限的正常接收,达到脉冲干扰抑制的目的。最后,通过算法实测验证算法的有效性。Pulse jamming as a common jamming mode,often affects the normal positioning of satellite navigation receiving equipment.In order to detect and suppress intentional or accidental pulse interference signals,a simple method of pulse interference identification and suppression is studied.The algorithm segments the signal within the statistical time,counts the maximum value and the minimum value of the maximum value of each segment of signal,looks for the initial threshold,and then statistics the adaptive pulse interference detection threshold.Sampling signals larger than the threshold are zeroed and normal reception of signals smaller than the threshold,achieve the purpose of pulse interference suppression.Finally,the effectiveness of the algorithm is verified by hardware test.
