I'm developing a radar project but I have a problem. The project
consists in the position (elevation and azimuth) and velocity
estimation of a target using a 2D array antenna. The DOA of the
signal reflected by the target has to be estimated using beamforming.
I'm reading something about DOA problem but any model is based on the
assumption that the signal trasmitted is a narrowband signal, a
complex sinusoide and in my case I have a chirp. What model do I have
to use in this case? I have to implement the beamformer in Matlab and
I should obtain something like a 2D FFT but I don't know how to go
on. If you have any suggestion, material or link please help me.
Thank you so much.
