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。
In order to meet the technical requirement of the differential transient injection experiment of complex transient electromagnetic pulse, the concept of complex transient injection waveform “effect characteristic parameter ” is proposed. The effect of each characteristic parameter on the disturbance and damage effect of weapon equipment is analyzed theoretically The principle of equivalent simplification of complex transient injection waveforms is proposed. An equivalent simplified method for two types of complex transient injection waveforms without carrier and carrier is proposed. Taking a certain type of data link transceiver system as the test object, Pulse Differential Pattern Directional Injection Equivalent Substitution Ultra Wide Band Electromagnetic Pulse Radiation Effect Experiment. The results show that the waveform parameters (ie, the characteristic parameters of the effects) that play a decisive role in the interference and damage of the weapon equipment mainly include signal amplitude, polarity, energy (pulse width), rise time, carrier frequency and pulse repetition frequency, Signal amplitude, positive and negative polarity, rise time, carrier frequency and pulse repetition frequency usually determine the interference effect of the device under test, and signal amplitude, positive and negative polarity, energy (pulse width) and carrier frequency usually determine the test Equipment damage effect; based on the principle of “strict equivalent”, “standard simplified” and “easy to implement”, “effective characteristic parameter” of complex transient injection waveform is taken as the equivalent basis to determine whether the trapezoidal or square wave pulse ) As the equivalent simplified injection waveforms. Under ultra-wide band electromagnetic pulse radiation and equivalent square wave pulse injection test conditions, the interference recovery time of a certain type of data link transceiver system is basically the same, and the experimental results verify the equivalent simplification of complex transient injection waveforms The effectiveness of the method. The results of this study provide theoretical and technical support for the study of the strong electromagnetic pulse effect of weapons and equipment.
