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

expand all

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

Output Arguments

expand all

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

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)
