This paper summarizes the techniques used during a microphone array test campaign performed at Pierre-Elliott-Trudeau Airport in Montréal, Québec (Canada) during the summer of 2012. Emphasis is put on the actual measurement campaign as only a limited amount of analysis has been performed at this stage. An aircraft position tracking tool is presented along with the beamforming algorithms that were used. Over 500 aircraft were recorded during this test. A comparison of known tonal sources associated to a specific aircraft type is made between different airlines in order to evaluate the repeatability of the method.
