I would like some advice on which beamforming method to use from someone with experience in the field.
I have radar data from the ocean which has been transmitted by an omnidirectional transmitter and received by a linear array of 8 antennas with half wavelength spacing.
The signals come from all directions and I need to separate them using beamforming.
I started by using a simple phase shift beamformer which I wrote in Python but it wasn't filtering the signals from other directions well.
I've found the Capon beamforming technique to be an improvement. There's a toolbox on MATLAB which provides good functions for doing this.
However, my questions are:
- What beamforming method would be best for this job?
- What are the pros and cons of the different methods?
If any more details are needed, please ask.
