Abstract

The synthesis of electromagnetic pulses with an extended spectrum is studied using summation of radiation pulses with different frequency bands in free space. The analytical estimation of the radiation spectrum with maximum width is performed for an array of combined antennas excited by bipolar pulses with durations of 0.5, 1, 2, and 3 ns. A combined antenna with an extended matching band is developed. The possibility to obtain ultrawideband radiation with a spectrum width of more than four octaves for an array of combined antennas excited by bipolar pulses with durations of 0.5, 1, 2, and 3 ns is experimentally demonstrated.

自由空间中不同频带电磁脉冲的合成

摘要

利用自由空间中不同频段的辐射脉冲之和，研究了具有扩展频谱的电磁脉冲的合成。对于宽度为0.5、1、2和3 ns的双极脉冲激发的组合天线阵列，进行了具有最大宽度的辐射谱的分析估计。开发了具有扩展匹配频带的组合天线。实验证明了对于由双极性脉冲持续时间为0.5、1、2和3 ns激发的组合天线阵列获得频谱宽度大于四个八度音阶的超宽带辐射的可能性。
