BeamformerMusic

class acoular.fbeamform.BeamformerMusic

Bases: acoular.fbeamform.BeamformerEig

Beamforming using the MUSIC algorithm, see ref:Schmidt, 1986<Schmidt1986>.

calc(ac, fr)

Calculates the MUSIC result for the frequencies defined by freq_data

This is an internal helper function that is automatically called when accessing the beamformer’s result or calling its synthetic() method.

Parameters:

ac : array of floats

This array of dimension ([number of frequencies]x[number of gridpoints]) is used as call-by-reference parameter and contains the calculated value after calling this method.

fr : array of booleans

The entries of this [number of frequencies]-sized array are either ‘True’ (if the result for this frequency has already been calculated) or ‘False’ (for the frequencies where the result has yet to be calculated). After the calculation at a certain frequency the value will be set to ‘True’

Returns:

This method only returns values through the ac and fr parameters
