Beamforming with Platform rotation

Hello,

From the stripmap SAR example, I've adapted it for having instead:

- tilted Tx/Rx antennas,

- a Tx with predefined look angle,

- Rx with beam scanning in elevation for the receiving echoes.

I am having trouble verifying everything is pointing at the right direction. How to easily check for instance the direction of the steered beams with respect to the global coordinate system?

Below is a piece of the code:

axis = roty(alpha); % platform rotation

radarPlatform = phased.Platform('InitialPosition',[0;-200;h_sar],'Velocity', [0;speed;0],'InitialOrientationAxes',axis)

% Transmit

w = (steervecTx(fc,[0;lookAngle]));

[targetRange, targetAngle] = rangeangle(targetpos,radarpos,axis);

sig = radiator(sig,targetAngle,w);

% Receive

scanAngle = [0;scangrid(scanid)];

ws = steervecRx(fc,scanAngle);

subarrayData = collector(sig,targetAngle,ws,scanAngle);

Thanks in advance.
