A simple procedure for tracking fast maneuvering aircraft using spatially distributed acoustic sensors
F. Dommermuth · The Journal of the Acoustical Society of America · 1987
Acoustical tracking of maneuvering aircraft based on bearing measurements from distributed sensors is not directly accessible to conventional techniques because of the retardation between emission and reception of sound. To overcome this complication, the following two-step strategy is proposed: (1) Estimate the aircraft location at an arbitrary time and repeat this procedure to obtain a sequence of position estimates; (2) combine these estimates by conventional filtering methods. Focusing on the first step, the localization problem is treated on the basis of at least two separated sensors that measure the direction of arrival of the incident sound wave. An assessment of the accuracy of the resulting position estimates is provided, as well. The procedure is illustrated both with simulated and real data.
