Delay-and-sum beamforming for arbitrary array geometry

Delay-and-sum response of multiple single frequency signals by using an arbitrary 1D, 2D or 3D array

This matlab function calculates the delay-and-sum response in the frequency domain of a discrete 1D, 2D or 3D array of any shape with isotropic elements. Input can consist of multiple sources of the same frequency arriving at different angles with different source power.
