getTaper

System object: phased.HeterogeneousULA
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 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

expand all

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

Examples

Heterogeneous ULA with Taylor Window Taper

Construct a 5-element heterogeneous ULA with a Taylor window taper. Then, obtain the element taper values.

sElement1 = phased.ShortDipoleAntennaElement(...
    'FrequencyRange',[100e6 1e9],...
    'AxisDirection','Z');
sElement2 = phased.ShortDipoleAntennaElement(...
    'FrequencyRange',[100e6 1e9],...
    'AxisDirection','Y');
sArray = phased.HeterogeneousULA(...
    'ElementSet',{sElement1,sElement2},...
    'ElementIndices',[1 2 2 2 1],'Taper',taylorwin(5)');
w = getTaper(sArray)
w =
