Abstract
The Acoustic Aircraft Detection (AAD) system developed by Stevens Institute of Technology for the detection of small aircraft in remote border areas was tested for tracking small aircraft in the airport. The goal of the test was to demonstrate a proof-of-concept capability for the acoustic sensor when applied to tracking aircraft during take off, landing, or taxing in a small airport. Two AAD nodes with five microphones were used to find the direction of arrival of sound produced by an aircraft using time-difference of arrival to pairs of sensors and to localize those by triangulation in real time. Additionally, a portable acoustic recorder system (PARS) with three microphones arranged in a ground plane was deployed to provide more data for post-processing analysis. The nodes separation varied between 150 and 250 m in different experiments. During the two-day experiment, aircraft activity of regular airport traffic was observed. At least 14 different aircraft were recorded during various movement on airport runways as well as takeoff and landing. The tested AAD was developed for another mission and was far from an optimal acoustic system for small airport applications. Suggestions for this system will be presented.
