Abstract
A system for generating a control signal comprises a data propagator (9) for propagating acoustic sensor array data relating to a set of acoustic measurements at a set of sensor positions covering an aperture towards a set of propagated positions to obtain propagated data relating to the set of propagated positions. A control signal generator (2) is arranged for generating a control signal based on the propagated data. The control signal generator (2) comprises a data analyzer (1) for analyzing the propagated data in a spatial frequency domain. The data propagator (9) is arranged for propagating the sensor array data in real-time and the control signal generator (2) is arranged for generating the control signal in real-time.
