getTaper

System object: phased.UCA
Namespace: phased

Array element tapers

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

H — Uniform circular array

System object™

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

Example: H = phased.UCA();

Output Arguments

WTS — Array element tapers

N-by-1 complex-valued vector

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

Examples

Show UCA Element Tapers

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

    0.4520
    0.9009
    1.3680
    1.5581
    1.3680
    0.9009
    0.4520

viewArray(sArray,'ShowTaper',true);

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