Patent GB-2170007-A (GB)
Title: Acoustic target locator
Inventor: GLASGOW JOHN ARTHUR
IPC: G01S3/808
Filed: 1985-10-25
Abstract: Two sound sensors A and B spaced by distance D listen for sounds within a wide band of wavelengths the shortest of which is substantially less than the distance band the longest wavelength of which is comparable with D. All the frequency components within that band from respective sensors are correlated at C1 to produce an output indicating the delay in the time of arrival of the signal at A relative to B. This delay is indicative of the direction of the target. The presence of a target is sensed by a level detector TD and causes the apparatus to become active transmitting signals from A and B in a direction, controlled by a variable delay VD, which is the same direction as that of the target. The transmitted signal irradiates the target more strongly so that periods between transmitted pulses can be used in the receiver to obtain more accurate direction information. Also, by correlating at C2 the transmitted and received signals range information can be obtained. The range and directional information is used to control a launching mechanism L. <IMAGE>
