Patterns of monopulse arrays with triangular amplitude distribution
Abstract
This paper describes the sum and difference patterns of monopulse linear arrays of equally spaced discrete inphase elements which are excited in such a way that the envelope of the excitation amplitudes is uniform, triangular, or Vshaped. The radiation patterns are analyzed by using exact or truncated Ztransform, and the compact form is obtained as S(z) = F(z)  G(z). S(z) can be found simply by the unilateral Ztransform without considering whether the envelope function is symmetrical or unsymmetrical. A numerical example is given showing that the theoretically calculated sum pattern compares quite favorably with that obtained from experiments.
