DETERMINING POSITIONS OF TRANSDUCERS FOR RECEIVING AND/OR TRANSMITTING WAVE SIGNALS

The invention is notably directed to a method for determining positions {pi}i=1,..., N of transducers {Ai}i=1,..., N of an apparatus. The transducers are assumed to be configured for receiving wave signals from and/or transmitting wave signals to one or more regions {Rm}m=1,..., M of interest in an n-dimensional space, with n = 2 or 3. The method first comprises determining an n-dimensional spatial filter function , which matches projections {Pm}m=1,..., M of the one or more regions {Rm}m=1,..., M of interest onto an n – 1-dimensional sphere centered on the apparatus. Then, a density function is obtained, based on a Fourier transform of the determined spatial filter function . Finally, a position pi is determined, within said n-dimensional space, for each of N transducers, based on the obtained density function and a prescribed number N of the transducers. The invention is further directed to related devices, apparatuses and systems, as well as computer program products.
