Abstract [en]

An implementation of an acoustic test-bed for direction- and location-finding is presented. The test-bed allows evaluation and testing of time difference of arrival (TDOA) techniques. A correlation-based method is used to estimate the TDOA between two time-synchronized and spatially separated receivers. A hyperbolic line then represents all possible transmitter positions for the estimated TDOA, which gives an asymptotic direction to the transmitter. When using three or more receivers a location may be estimated. Measurement show that the test-bed performs satisfactory for direction- and location-finding and works as a flexible platform for evaluating TDOA estimations.
