摘　　要：针对复杂瞬态电磁脉冲差模定向注入试验的技术需求,提出了复杂瞬态注入波形"效应特征参量"的概念,理论分析了各效应特征参量对武器装备干扰和损伤效应的影响,给出了复杂瞬态注入波形等效简化的原则,提出了不带载波和带载波的两类复杂瞬态注入波形的等效简化方法,以某型数据链收发系统为受试对象,开展了电磁脉冲差模定向注入等效替代超宽带电磁脉冲辐射效应试验。研究结果表明:对武器装备的干扰或损伤起决定性作用的波形参量(即效应特征参量)主要包括信号幅度、正负极性、能量(脉宽)、上升时间、载波频率和脉冲重复频率等,其中信号幅度、正负极性、上升时间、载波频率和脉冲重复频率通常决定了受试设备的干扰效应,而信号幅度、正负极性、能量(脉宽)和载波频率通常决定了受试设备的损伤效应;基于加严等效、标准简化和易于工程实现原则,以复杂瞬态注入波形的"效应特征参量"作为等效依据,确定将梯形波或方波脉冲(含带载波)作为等效简化注入波形;在超宽带电磁脉冲辐射和等效方波脉冲注入试验条件下,某型数据链收发系统的干扰恢复时间基本相同,试验结果验证了复杂瞬态注入波形等效简化方法的有效性。该研究结果为武器装备的强电磁脉冲效应研究提供了理论和技术支撑。According to the requirements of differential mode directional injection test for complex transient electro- magnetic pulse, we proposed a new concept of effect characteristic parameter of the complex transient injection waveform. Moreover, we theoretically analyzed the influences of the effect characteristic parameters on the interference and damage of the weaponry, and presented an equivalent simplification principle of the complex transient injection waveforrn. Meanwhile, we put forward the equivalent simplification methods of the complex transient injection wave- foma in the presence or absence of carrier ,respectively. The certain type data link transmit-receive system was selected as EUT. The electromagnetic pulse differential mode directional injection equivalent of ultra-wide band electromagnetic pulse radiation were tested. The research results indicate that the waveform effect characteristic parameters which play an important role in the interference and damage are as follows： signal amplitude, positive-negative polarity, energy （pulse width）, rising time, carrier frequency, and pulse repetition frequency. The interference effects of the EUT are decided by signal amplitude, positive-negative polarity, rising time, carrier frequency, and pulse repetition frequency. The damage ef- fects are decided by signal amplitude, positive-negative polarity, energy （pulse width）, and carrier frequency. Based on the principle of the tightened equivalence, standard simplification and engineering realization easily, the trapezoidal wave and square wave pulse which may include carrier are confirmed to be the equivalent simplification injection waveform in ac- cordance with the equivalent condition of the same effect characteristic parameters. Under the condition of the ultra-wide band electromagnetic pulse radiation and differential mode directional injection, the interference recovery time of the cer- tain type data link transmit-receive system is ahnost the same. The test results verify the effectiveness of t
