PowerSpectraobject that provides the cross spectral matrix and eigenvalues, is set automatically.
Flag, if ‘True’ (default), the main diagonal is removed before beamforming, is set automatically.
SteeringVectoror its derived classes, that contains information about the steering vector. Is set automatically.
eva_list= CArray(dtype=int, …¶
List of components to consider, use this to directly set the eigenvalues used in the beamformer. Alternatively, set
sets the list of eigenvalues to consider
Calculates the Orthogonal Beamforming result for the frequencies defined by
- 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
