getTaper
System object: phased.HeterogeneousURA
Namespace: phased
Array element tapers
Syntax
wts = getTaper(h)
Description
returns
the tapers, wts
= getTaper(h
)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
