Design of a Phase Calibrator to Evaluate Non-Matched Microphones for Intensity Probes
Applied Sciences, 2023 Intensity measurements represent a well-established method to determine the sound power of an emitting object. The principal strength of this technique relies upon the possibility of performing the measurements in situ, with no special required ...

Multisource Self-calibration for Sensor Arrays [PDF]
, 2009 Calibration of a sensor array is more involved if the antennas have direction dependent gains and multiple calibrator sources are simultaneously present. We study this case for a sensor array with arbitrary geometry but identical elements, i.e.
