Abstract :
An acoustic source generates an amplitude-modulated tone, with Doppler variations due to the relative motion between source andreceiver. A method is presented for real-time estimation of tone restfrequency and minimal distance between source and receiver, usingdigital signal processing techniques. The algorithm presented herewas implemented using a Texas Instruments TMS32010 processor.
