Phased Array Design Toolbox v2.5



10 Feb 2009 (Updated )

A toolbox allowing rapid definition and evaluation of 2D and 3D phased array antennas.

% Example showing the use of the circ_array and taywin_array functions.
% A circular array of 48 patches in 4 rings is defined. Then an
% amplitude taper based on the Taylor distribution is applied as
% a function of radius. The target 1st sidelobe level is -25dB relative
% to the main lobe peak.
% Note that the Taylor distribution assumes isotropic sources, the 
% slight reduction in the 1st sidelobe level (compared to -25 requested)
% is due to the patch element pattern.
