Intro:
For reasons I won't enumerate, I must import an Antenna Toolbox generated pattern() into Phased Array Toolbox by means of a CustomAntennaElement object:
az = -180:5:180;
el = -90:5:90;
dblpatch = customAntennaGeometry;
gain = pattern(dblpatch,freq,az,el);
elem = phased.CustomAntennaElement('AzimuthAngles',az,'ElevationAngles',el, ...
'MagnitudePattern',gain,'PhasePattern',zeros(dimEl,dimAz));
This seems to work fine,but when I build a URA the pattern comes out goofy. Here's the array code:
array = phased.URA;
array.ArrayNormal = 'z';
array.Element = elem;
array.Size = size;
array.ElementSpacing = [spacing spacing];
Basically, I believe that I need to rotate the dblpatch (AT) radiation pattern so that the max directivity is along the x axis, instead of the z-axis, then change to array.ArrayNormal = 'x'
How would one go about doing this?
Results:
Five figures are attached: four rad patterns (antenna & phased array toolbox elements and arrays) and the PA toolbox array's lattice.
Current idea fragments:
- phitheta2azel()
- circshift() & other manual array manipulation
I cannot use the AT element's Tilt or TiltAxis properties.
