BeamformerTimeTraj

class acoular.tbeamform.BeamformerTimeTraj

Bases: acoular.tbeamform.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.

result(num=2048)

Python generator that yields the beamformer output block-wise.

Optional removal of autocorrelation. The “moving” grid can be translated and optionally rotated.

Parameters:
num : integer, defaults to 2048

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

Returns:
Samples in blocks of shape (num, :attr:`~BeamformerTime.numchannels`).

numchannels is usually very large (number of grid points). The last block may be shorter than num. The output starts for signals that were emitted from the grid at t=0.
