Syntax

wts = getTaper(array)

Description

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

Input Arguments

expand all

Heterogeneous uniform line array, specified as a phased.HeterogeneousULA System object.

Output Arguments

Construct a 5-element heterogeneous ULA with a Taylor window taper. The array consists of short-dipole antenna elements with different orientations.Then, obtain the element taper values.

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