摘要：

- In view of the challenges and difficulties encountered in the analysis and application of time- driven ultra-wideband array antennas (TD-UWB arrays), this study investigates the pulse radiation characteristics of discretized apertures based on aperture radiation theory and space superposition principle. The impact of discretized aperture linear arrays and planar arrays to restore the radiation of original aperture is examined, along with an analysis of how discretization methods influence the radiated pulse waveforms. The potential application of discretized aperture radiation in research of TD-UWB array antennas is studied, and a method is proposed for predicting time-domain radiation characteristics of TD-UWB arrays. Numerical results demonstrate that the proposed method derived from the discretized aperture radiation can effectively predict the temporal pattern and radiation waveforms of TD-UWB arrays. The research expands and advances the practical applications of aperture radiation, thereby offering a novel perspective for analyzing the radiation characteristics of TD-UWB arrays.
