Abstract

The optimum solution for the transient radiation from a dipole array is derived in terms of the time-domain voltages which are required at the input terminals of dipoles in an array so that the amplitude of the transient radiated field at a specified time $t_{0}$ and far-field position $r_{0}$ , $\\theta_{0}, \\phi_{0}$ is maximized. Constraints are placed on the energy and bandwidth of the input signal voltages with current restricted by Pocklington\´s equation. Further constraints on the sidelobe level are used to obtain a modified solution for suppressed sidelobes in the radiation pattern. Results of numerical optimization are presented, and the effects of scan angle, element spacing, and a sidelobe constraint on the optimization are discussed.
