| 摘 要： | 由电磁场理论给出了平面线元天线阵列辐射的瞬态电磁脉冲沿径向坡印亭矢量时间积分的解析解及数值解结果,并利用物理光学理论对所得结果作了对比分析,得到结论:(1)线元天线阵列辐射问题可以简洁地由光栅方程求解;(2)被约束波束的坡印亭矢量时间积分的最大值与阵元数目的平方成正比;(3)保持同一列辐射器元馈电同步,而沿行方向依次作适当馈电时间延迟,可有效将波束控制在预期的很小角域内;(4)保持扫描的半角宽度,线元天线阵列有确定的波束扫描角范围。 |

| Abstract: | Based on electromagnetic theory, the analytical and numerical results of radial energy of linear element planar antenna array excited by electromagnetic pulse; are offered at first, then, by analyzing the results with the interference and the diffraction theories, following conclusions are got: (1) The electromagnetic radiation problem of plane linear element planar antenna array can be solved by grating equation concisely. (2) The maximum energy of bounded beam is proportional to the square of the number of element of antenna array. (3) Keeping the same line elements of antenna array feeding at the same time while each row successive postpone properly, the beam can be restrained within the expected area. (4) The effective scanning angle range depends on the given half angle width. |
