BeamformerTimeSqTraj¶

class acoular.tbeamform.BeamformerTimeSqTraj¶

Bases: BeamformerTimeSq, BeamformerTimeTraj

Provides a time domain beamformer with time-dependent power signal output and possible autopower removal for a grid moving along a trajectory.

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, num_channels).

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