Syntax

WTS = getTaper(H)

Description

WTS = getTaper(H) returns the tapers, WTS, applied to each element of the phased uniform circular array (UCA), H. Tapers are often referred to as weights.

Input Arguments

expand all

Uniform circular array, specified as a phased.ULA System object.

Example: H = phased.UCA();

Output Arguments

expand all

Array element tapers, returned as an N-by-1 complex-valued vector, where N is the number of elements in the array.

Construct a 7-element UCA array of isotropic antenna elements with a Taylor window taper. Design the array to have a radius of 0.5 meters. Then, draw the array showing the element taper shading.

Nelem = 7;
R = 0.5;
taper = taylorwin(Nelem);
sArray = phased.UCA(Nelem,R,'Taper',taper.');
w = getTaper(sArray)
w = 7×1

Figure contains an axes object. The hidden axes object with xlabel x axis (Az 0 El 0) -->, ylabel y axis --> contains 8 objects of type scatter, line, text.

Both the output and figure above shows that the taper magnitudes are largest near the middle element.
