Abstract

Measurements were made on three cables in the electromagnetic pulse (EMP) testbed aircraft (EMPTAC) using the horizontally polarized dipole (HPD) and TRESTLE EMP simulators as well as the random repetitive square-wave pulse generator (R/sup 2/SPG) and a damped sine-wave generator. The currents were analyzed in both the time and frequency domains. The R/sup 2/SPG produced a greater induced current, by a factor of 4 to 60, than either of the EMP simulators. The pulsewidths and the frequency content were similar for all of the test points obtained with the R/sup 2/SPG and EMP simulators, and, by careful selection of the charge and feed cables, cold be made essentially identical. This confirms the assumption that the R/sup 2/SPG excited the cable system at its resonant frequency. The amplitudes of the R/sup 2/SPG and the damped sine-wave generator were closer to each other in both the time and frequency domains. The damped sine-wave generator was able to couple more energy to the cable when the lowest carrier frequencies (0.1 and 1 MHz) were used. On the other hand, the damped sine-wave current transient had a much narrower bandwidth than the R/sup 2/SPG-induced current transient. Thus the R/sup 2/SPG waveform was much more suitable for upset testing than the damped sine-wave.<>

R/sup 2/SPG波形与仿真EMP的比较

使用水平极化偶极子(HPD)和TRESTLE电磁脉冲模拟器以及随机重复方波脉冲发生器(R/sup 2/SPG)和阻尼正弦波发生器对电磁脉冲(EMP)试验台飞机(EMPTAC)中的三根电缆进行了测量。对电流进行了时域和频域分析。R/sup 2/SPG产生的感应电流比任何一个EMP模拟器都要大，是4到60倍。使用R/sup 2/SPG和EMP模拟器获得的所有测试点的脉冲宽度和频率含量相似，并且通过仔细选择充电和馈电电缆，可以使其基本相同。这证实了R/sup 2/SPG以其谐振频率激励电缆系统的假设。R/sup 2/SPG和阻尼正弦波发生器的振幅在时域和频域上更接近。当使用最低载波频率(0.1和1 MHz)时，阻尼正弦波发生器能够将更多的能量耦合到电缆上。另一方面，阻尼正弦波电流瞬态比R/sup 2/ spg感应电流瞬态具有更窄的带宽。因此，R/sup 2/SPG波形比阻尼正弦波更适合于扰动试验。
