Abstract
A method and system for detecting a signal source at a specified frequency in the presence of background noise includes a processor; a first sensor mounted at a first location operatively connected to the processor; a second sensor mounted at a second location operatively connected to the processor; the processor operating to compute the amplitudes of the first and second Fourier transforms of the outputs of the first and second sensors, respectively, the difference in the amplitudes of the first and second Fourier transforms being determinative of the existence of a signal being generated at the predetermined frequency.
