Abstract
A system for determining the direction of an underwater discrete source of acoustic vibrations by sensing acoustic wavefronts produced thereby, which system comprises a neutrally buoyant semirigid underwater platform which may be made of a water inflated soft walled material and having mounted thereon an array of omnidirectional hydrophones arranged in a predetermined geometric pattern. Circuit means are connected to the hydrophones and an array steering means is associated with the circuit means to allow determination of the time relationship of the signals obtained from the hydrophones.
Claims15
A system for determining the direction of an underwater discrete source of acoustic vibrations by sensing acoustic wavefronts produced thereby, comprising a semirigid generally neutrally buoyant underwater platform made of a water inflated soft walled element, an acoustic wavefront sensing array of at least three omnidirectional hydrophones mounted on said platform in a preselected geometric arrangement, and a telemetry link including transmitting means and receiving means, said transmitting means being connected to said hydrophones, and array steering means connected with said receiving means to allow determination of the time relationship of the signals obtained from said hydrophones.
