I have a Matlab phased array toolbox question that I hope that someone here is able to help with. I modified the code given via examples to suit my environment.
I'm modelling a base station set up at origin with a client on a moving platform transmitting a narrowband signal. The base station is there to collect and determine the direction of arrival of the signal from the moving platform.
I've tried to model it but I can't seem to figure out how to model the narrowband emitter onto the platform and the scenario.
I hope a kind soul is able to help.
Thank you.
