class acoular.fbeamform.BeamformerFunctional

Bases: BeamformerBase

Functional beamforming after Dougherty, 2014.

gamma = Float(1, desc='functional exponent')

Functional exponent, defaults to 1 (= Classic Beamforming).

r_diag = Enum(False, desc='False, as Functional Beamformer is only well defined for the full CSM')

Functional Beamforming is only well defined for full CSM

calc(ac, fr)

Calculates the Functional Beamformer 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.

acarray 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.

frarray 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’

This method only returns values through the ac and fr parameters
