Antenna patterns of nonsinusoidal waves with the time variation of a Gaussian pulse II

For pt.I see ibid., vol.30, no.4, p.504 (1988). In Part I of this series of papers, antenna patterns for nonsinusoidal waves with the time variation of a Gaussian pulse, received (or radiated) by a linear array of sensors (or radiators) were derived. Computer plots of the peak-amplitude pattern, peak-power pattern, energy pattern, and slope pattern were presented. In this paper, the above antenna patterns are derived for a planar array of sensors (or radiators) receiving (or radiating) Gaussian pulses. Based on the characteristics of the Gaussian pulse, which are presented in Part I, the principle of frequency-domain array beam forming with Gaussian pulses is described. An expression for the antenna energy pattern based on the frequency-domain analysis is derived and plotted for comparison to the one obtained in Part I from the time-domain analysis
