摘要

考虑到辐射波电磁脉冲模拟器笼形天线尺寸过大、在单个微机上计算其辐射特性的时间过长及内存受限制,使用基于消息传递接口(MPI)平台的用于同轴线馈电的时域有限差分并行算法,并结合天线理论模拟分析了同轴线馈电的辐射波电磁脉冲模拟器双锥笼形天线在双指数脉冲电压激励下的脉冲辐射特性。并行时域有限差分计算时,整个时域有限差分计算区域的网格总数约为20亿。由计算结果分析可知:当锥半径大于3.5 m后,笼形天线的半径大小对电场的上升沿和峰值的影响不大;对地面上方0.5 m处的几个测试时,其上升沿、半高宽及脉冲峰值受地面反射及地面损耗的影响比较大,而对于地面上方6 m处的几个测试点,除半高宽外,几个测试点的辐射场脉冲峰值及上升沿受地面影响较小;离地面越近的点,峰值减小得越快。

Abstract

A parallelized finite-difference time-domain(FDTD) algorithm based on MPI platform, combined with antenna theory, is presented for analysis of the radiation characteristics of the large biconical-cylindrical cage antenna fed through the coaxial transmission line and excited by a double-exponential pulse, which can not be done on a personal computer due to long time and limited computation resources. The number of total cells for parallelized FDTD computing is about 2 billion. Numerical results show that cage antenna radius do not have a significant effect on the rise time and the peak value of the radiated electric field when the cage antenna radius is more than 3.5 m. In addition, the reflection and the loss from the ground have a great effect on the peak value and pulse width of the radiated E-field in the horizontal plane above the ground up to 0.5 m and have little effect on the rise time and the peak value of the radiated E-field in the horizontal plane above the ground up to 6 m except the pulse width of the radiated E-field at the same point. It is found that the nearer to the ground, the faster the decrease of the peak value.
