BeamformerTimeSq¶

class acoular.tbeamform.BeamformerTimeSq¶

Bases: BeamformerTime

Provides a time domain beamformer with time-dependend power signal output and possible autopower removal for a spatially fixed grid.

r_diag = Bool(True, desc='removal of diagonal')¶

Boolean flag, if ‘True’ (default), the main diagonal is removed before beamforming.

result(num=2048)¶

Python generator that yields the squared time-domain beamformer output.

The squared output time signal starts for source signals that were emitted from the Grid at t=0.

Parameters:

numint

This parameter defines the size of the blocks to be yielded (i.e. the number of samples per block). Defaults to 2048.

Yields:

numpy.ndarray

Samples in blocks of shape (num, numchannels).

numchannels is usually very large (number of grid points). The last block returned by the generator may be shorter than num.
