Signal integrity in pulse-train excited array antennas in time and space - a full TD analysis

Signal integrity in the far-field radiation from pulse-train excited array antennas is studied via full time-domain instruments. The disturbance in the received signal is related to the fidelity factor. At any point in our analysis, the disturbance is evaluated based on a reduced, well defined set of parameters: pulse parameters and pulse repetition rate - temporal dependence, and elementary radiator location - spatial dependence. Their effect is examined by means of illustrative numerical experiments. These results are expedient for enhancing the detectability of the signals radiated by pulse-train excited array antennas, as needed in wireless digital transfer.
