| 摘 要： | 首次在球坐标系统下研究了电磁导弹有趣的波瓣特性。研究表明:当天线口径、距离一定时,电磁导弹的波瓣随波形参量减小而变窄;当天线口径、波形参量一定时,电磁导弹的波瓣随距离增加而变窄;当波形参量、距离一定时,电磁导弹的波瓣随天线口径增加而变宽;电磁导弹不存在副瓣;电磁导弹的能量在远轴时仍按球面波方式衰减。这些结论有助于理解电磁导弹的实质。

| Abstract: | The interesting pattern characteristics of electromagnetic (EM) missiles in spherical coordinates is investigated for the first time. The results shows that when the antenna dimiension and the distance are fixed, the lobe of the EM missile becomes narrow with the decrease of the waveform parameter, it also goes narrow with the increase of the distance provided the other two parameters are invaniant, it will widen as the antenna d?ension increases with the others fixed. Moreover, no sidelobes exist in the pattern of EM missiles and the energy of the EM missile in far-axis region drops off as the same as that of the spherical wave.These conclusions are quite helpful to undrstand the mechunism of EM Missiles. |
