isPolarizationCapable

System object: phased.HeterogeneousConformalArray
Package: phased

Polarization capability

Syntax

flag = isPolarizationCapable(h)

Description

flag = isPolarizationCapable(h) returns a Boolean value, flag, indicating whether the array supports polarization. An array supports polarization if all of its constituent sensor elements support polarization.

Input Arguments

expand all

h — Conformal array

Conformal array specified as a phased.HeterogeneousConformalArray System object™.

Output Arguments

expand all

flag — Polarization-capability flag

Polarization-capability returned as a Boolean value true if the array supports polarization or false if it does not.

Examples

Conformal Array of Short-dipole Antenna Elements Supports Polarization

Show that a circular conformal array of phased.ShortDipoleAntennaElement antenna elements supports polarization.

sElement1 = phased.ShortDipoleAntennaElement(...
    'FrequencyRange',[100e6 1e9],...
    'AxisDirection','Z');
sElement2 = phased.ShortDipoleAntennaElement(...
    'FrequencyRange',[100e6 1e9],...
    'AxisDirection','Y');
elemAngles = ([0:5]*360/6);
elemPosInner = 0.5*[zeros(size(elemAngles));...
    cosd(elemAngles); sind(elemAngles)];
elemPosOuter = [zeros(size(elemAngles));...
    cosd(elemAngles); sind(elemAngles)];
elemNorms = repmat([0;0],1,12);
sArray = phased.HeterogeneousConformalArray(...
    'ElementSet',{sElement1,sElement2},...
    'ElementIndices',[1 1 1 1 1 1 2 2 2 2 2 2],...
    'ElementPosition',[elemPosInner,elemPosOuter],...
    'ElementNormal',elemNorms);
isPolarizationCapable(sArray)
ans =

     1

The returned value true (1) shows that this array supports polarization.
