A simple "ad hoc" method is presented which it allows to calibrate arrays of sensors, as much in transmission as in reception, for narrow-band acoustical radar systems, using beamforming techniques, where does not know the phase and gain characteristics of each one of the channels. Three methodologies of calibration are proposed, testing on a real system, analyzing the degradation introduced on the radiation patterns, based on the type of calibration and appointment angle values.
