BeamformerTimeTraj

class acoular.tbeamform.BeamformerTimeTraj

Bases: BeamformerTime

Provides a basic time domain beamformer with time signal output for a grid moving along a trajectory.

trajectory = Trait(Trajectory, desc='trajectory of the grid center')

Trajectory or derived object. Start time is assumed to be the same as for the samples.

rvec = CArray(dtype=float, shape=(3,), value=array((0, 0, 0)), desc='reference vector')

Reference vector, perpendicular to the y-axis of moving grid.

conv_amp = Bool(False, desc='determines if convective amplification of source is considered')

Considering of convective amplification in beamforming formula.

precision = Trait(64, [32, 64], desc='numeric precision')

Floating point and integer precision

result(num=2048)

Python generator that yields the time-domain beamformer output.

The 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.
