Beam shaping using nonlinear phase distribution in a uniformly spaced array

The method of determination of the phase distribution of a linear array of discrete sources for a specified radiation pattern and a fixed aperture amplitude function is presented. The finite series representing the array factor is transformed into an infinite series each term of which is in the form of an integral. Synthesis is carried out from asymptotic evaluation of the integral by the stationary phase method. Computed results for sector and cosecant beam are presented.
