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 yaxis of moving grid.

result
(num=2048)¶ Python generator that yields the beamformer output blockwise.
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.
