Wrapper around kernel.beamform that includes coherent compounding.

The implementation takes some shortcuts for quick prototyping.

Parameters:

• channel_data – like kernel.beamform channel_data, but with an extra first dimension for transmits

• tx_wave_arrivals_s – like kernel.beamform tx_wave_arrivals_s, but with an extra first dimension for transmits

See kernel.beamform for other argument descriptions.

Returns:

beamformed+compounded data with shape (n_points, n_frames)
