Acoustical tracking of fast maneuvering aircraft by distributed sensors
Abstract
A method for the aeroacoustic tracking of nearly arbitrarily maneuvering subsonic sound sources is presented. With the proposed procedure, the target position can be determined at any instant, if the measured data of at least two acoustical sensors (consisting of three or four microphones each) are available. The pertaining error covariance matrix is given. The application to simulated data shows that even very fast maneuvering targets can be tracked reliably. A data update rate of 5 Hz allows a near real time tracking, including the extensive measuring data treatment of four sensors. The application to real data is shown to have good results.
