摘　　要：为研究电磁脉冲串对数字通信电台的阻塞效应机理,以某型数字通信电台为受试对象,通过电磁脉冲注入试验,研究了受试电台误码率随电磁脉冲串幅值、重复间隔时间的变化规律。结果表明,随着脉冲幅值的增大,误码率先单调上升再以不同规律变化;不同脉冲重复率下受试电台的敏感误码率相差较大,敏感误码率不能用固定数值作为敏感判据,但利用敏感误码率与脉冲重复率成正比作为判据则具有较高的准确度,据此给出了受试数字电台的误码率敏感判据及试验方法,以通过部分试验数据获取任意脉冲重复率下的误码率敏感判据。In order to study the blocking effect of digital communication stations radiated by electromagnetic pulse trains,an electromagnetic pulse injection test was performed on a digital communication station. The bit error rate（ BER） of radio stations following the change of amplitude and repeat interval of electromagnetic pulse trains was studied. The results show that the BER increase monotonously at the beginning and then changes in different ways with the increase of pulse amplitude. Because there is big different in BER when the pulse repetition rate is different,a certain BER cannot be used as a susceptibility criterion. But according to the relationship between the BER and the pulse repetition rate,the susceptibility criterion of BER under any repetition rate can be given.
