METHOD OF CHECKING THE DIRECTIVITY AND POLARIZATION OF COHERENT FIELD DISTRIBUTIONS IN A REVERBERANT MEDIUM

摘要

The invention relates to a method for generating and checking a spatio-temporal field distribution having predefined characteristics such as one or more directions of propagation, a high level of field intensity and a polarization in a reverberant chamber. To do this, two separate networks of transducers are provided so as to estimate a transfer function between these two networks and to determine excitation signals using the principle of temporal return. The excitation signals are used to generate the spatio-temporal field according to the predefined characteristics.
