Energy Pattern Beamwidth of Linear Antenna Excited By Asymmetric Exponential Pulse

摘要

In this paper, analysis of energy pattern beamwidth for linear antenna excited synchronously by asymmetric exponential pulse is presented. Estimates, those are based on approximate relations, are derived and discussed. It is shown that relationships between dimensions of radiating surface, pulse spatial duration and energy pattern beamwidth for different types of exciting signals are in fact uncertainty relations. Expressions obtained allow to evaluate the energy pattern beamwidth of linear antenna excited synchronously by asymmetric exponential pulse, symmetric exponential pulse and step signal with finite duration of leading edge promptly. The formulas obtained with respect to the numerical solution give the errors in the 1.4-10% range.
