Phase spoiling for beam broadening

Hello,

I'm struggling to model broadening of a URA pattern with phase spoiling techniques.

Are there any examples with beam shaping using Phased Array objects?

Thanks.

I am not sure about Phased Array Toolbox but following example might help you:

While specific examples of phase spoiling might not be directly available, you can modify beamforming examples to include phase spoiling. This involves adjusting the phase of each element in the array to achieve the desired pattern broadening. Use functions like phased.URA and phased.PhaseShiftBeamformer to create and manipulate URAs (Uniform Rectangular Arrays) and apply phase shifts. If you need to implement phase spoiling specifically, you might need to manually adjust the phase of each element in the array. This can be done by modifying the steering vector or weights applied to the array elements.

The following example provides an introduction to beam spoiling, those codes can be used with phased array objects. These are certainly not the only technique used in the field, but they serve as a good starting point. Please let me know if you need any additional information.
