System object: phased.ConformalArray Package: phased
Array element tapers
wts = getTaper(h)
wts = getTaper(h) returns the tapers applied to each element of a conformal array, h. Tapers are often referred to as weights.

phased.ConformalArray
Conformal array specified as a phased.ConformalArray System object™.
Array element tapers returned as an N-by-1, complex-valued vector, where N is the number of elements in the array.
Create a two-ring tapered disk array
Create a two-ring disk array and set the taper values on the outer ring to be smaller than those on the inner ring.
elemAngles = ([0:5]*360/6); elemPosInner = 0.5*[zeros(size(elemAngles));... cosd(elemAngles);... sind(elemAngles)]; elemPosOuter = [zeros(size(elemAngles));... cosd(elemAngles);... sind(elemAngles)]; elemNorms = repmat([0;0],1,12); taper = [ones(size(elemAngles)),0.3*ones(size(elemAngles))]; ha = phased.ConformalArray(... [elemPosInner,elemPosOuter],elemNorms,'Taper',taper);
Display the taper values
w = getTaper(ha)
w = 12×1 1.0000 1.0000 1.0000 1.0000 1.0000 1.0000 0.3000 0.3000 0.3000 0.3000 ⋮
View the array
viewArray(ha,'ShowTaper',true,'ShowIndex','all');
