本文给出了一个适用于计算线元面阵结构上瞬态响应电流的积分方程。求取了线元面阵的电流分布和辐射场。讨论了近似求取由短振子组成的大阵的瞬态响应的方法。讨论了数值结果的稳定性和收敛性的检测。比较了求瞬态响应的时域计算时间和频域计算时间。

An integral equation which is convenient to calculate the transient response of dipole arrays is developed. The current distribution and radiated field of planar antenna arrays of straight-wire coupled antennas are calculated in the time domain especialy for short dipoles. The approximate method determining the transient response of large antenna arrays composed of short dipoles is discussed. The numerical results are interpreted in detail. The test about stability and convergence of numerical solution are carried out. The calculating time for transient response between time domain and frequency domain is compared.
