Abstract
A signal processor for obtaining frequency and bearing information of an ustical signal. Responsive to the acoustical signal, a multimode hydrophone generates a plurality of electrical signals which are combined to form a first omnidirectional signal and two spatially orthogonal directional signals. The directional signals are then combined to form a second omnidirectional signal. Additional circuitry is provided to analyze the two omnidirectional signals using the cross-spectral density function of the two omnidirectional signals to obtain said frequency and bearing information.
