getTaper

System object: phased.HeterogeneousURA
Package: phased

Array element tapers

Syntax

wts = getTaper(h)


Description

wts = getTaper(h) returns the tapers, wts, applied to each element of the phased heterogeneous uniform rectangular array (URA), h. Tapers are often referred to as weights.

Input Arguments

h — Uniform rectangular array

phased.HeterogeneousURA System object™

Uniform rectangular array specified as a phased.HeterogeneousURA System object.

Output Arguments

wts — Array element tapers

N-by-1 complex-valued vector

Array element tapers returned as an N-by-1, complex-valued vector. The dimension N is the number of elements in the array. The array tapers are returned in the same order as the element indices. The element indices of a URA run down each column, then to the top of the next column to the right.

Examples

Heterogeneous URA Array Element Tapering

Construct a 2-by-5 element heterogeneous URA with a Taylor window taper along each row. Then, show the array with the element taper shading.

antenna1 = phased.ShortDipoleAntennaElement('FrequencyRange',[100e6 1e9], ...
    'AxisDirection','Z');
antenna2 = phased.ShortDipoleAntennaElement('FrequencyRange',[100e6 1e9], ...
    'AxisDirection','Y');
array = phased.HeterogeneousURA('ElementSet',{antenna1,antenna2},...
    'ElementIndices',[1 2 2 2 1 ; 1 2 2 2 1],...
    'Taper',[taylorwin(5)';taylorwin(5)']);
w = getTaper(array)

w = 10×1
