摘要： An acoustic reflector is described comprising a shell around a core, in which portions of the shell are capable of transmitting acoustic waves incident on the shell into the core to be focused and reflected from an area of the shell located opposite to the area of incidence of the acoustic waves to provide a reflected acoustic signal output from the reflector. Incident acoustic radiation will be differentially reflected depending on the portion of the reflector on which the incident acoustic radiation impinges.

摘要： A marker to mark underwater objects characterised in that it undergoes whole body resonance when exposed to an incident acoustic wave. In one arrangement the marker comprises a shell surrounding a water core. In other arrangements the marker is toroidal or cylindrical or tubular in shape. Holes are provided in the shell to allow water freely to enter and leave the core when the marker is immersed in water. In the case of cylindrical or tubular shells, the cylinders or tubes can be open ended to allow water freely to flow into the interior of the shell. Best results are obtained when the marker is a sphere of aluminium, aluminium alloy or brass between 200mm and 400mm inclusive in diameter with a shell wall between 6mm and 15 mm inclusive thick, operating with an interrogating sonar or other acoustic transducer at 30 to 80KHz inclusive.

摘要： An acoustic reflector primarily for underwater use comprising a shell surrounding a core in which holes are provided in the shell to allow air and water freely to enter and leave the interior of the shell when the reflector is immersed in water. Various embodiments are described including the use of a metal shell matched to a water core, the use of a mounting bar, provision of a frame to reflect acoustically alpha numeric characters, a soluble plug to delay operation of the reflector, and coating the reflector with polyurethane to limit damage. Also proposed is a pulse pattern to improve the identification of an acoustic reflector in some circumstances. Designs of reflectors particularly suitable for use with the relatively low frequency sonars found in the fishing industry with an aluminium or aluminium alloy shell are described, as are reflectors with a non-metal shell suitable for use with the higher frequency sonars in the underwater exploration industry. The reflectors can be spherical, toroidal, ovoid, or cylindrical provided that they have at least on circular cross section. A particularly important development with the current invention is the ability to mark and trace underwater non-ferromagnetic pipes.

摘要： A passive acoustic reflector for use under water having a non-metallic shell characterised in that it has a circular cross section and has a hole (18) in the shell (12) said hole (18) having a larger diameter on its outside (24) than its inside (22), and is plugged with a plug (20, 30) whose outer dimensions provide a tight fit within the hole. Various forms of reflector as discussed. The invention also describes the creation of a field of dissimilar reflectors for navigation purposes. In one embodiment passive reflectors, two of one diameter, and one of another are mounted on a trident. In another embodiment a set of reflectors is laid in a field. The reflectors reflect interrogating sonar at certain predetermined frequencies, the reflected frequency pattern being unique within the field for each reflector.

摘要： An acoustic reflector comprises a shell surrounding a core, said shell being capable of transmitting acoustic waves incident on the surface of the shell into the core to be focused and reflected from an area of the shell located opposite to the area of incidence so as to provide a reflected acoustic signal output from the reflector, having a core in which the shell is dimensioned relative to the core such that a portion of the acoustic waves incident on the shell wall are coupled into the shell and guided therein around the circumference of the shell and then re- radiated to combine constructively with the said reflected acoustic signal output so as to provide an enhanced reflected acoustic signal output. The ratio of the speed of sound wave transmission in the shell to the average speed of the wave transmission in the core is preferably in the range of 2.74 to 3.4, inclusive with best result in the range of 2.74 to 2.86 inclusive. Applications to underwater pipelines are described, scouring measurement and arrays of reflectors are also described along with novel methods of construction of such reflectors.

摘要： A method of identifying and locating an acoustic reflector is described by interrogating underwater objects with a sonar and deploying one or more of the steps of a. identifying objects that apparently reflect the acoustic interrogation with a double echo, measuring the separation of the two echoes and comparing those measurements with anticipated measurements for underwater acoustic reflectors that may be present in the search area, and accepting or rejecting the reflected acoustic wave as potentially including the echo from the front of such an acoustic reflector and the echo from the shell at the rear of the reflector; b. measuring the target strength of the echoes in a double echo received from an object and rejecting the object as one of interest if the target strength in the first echo of a double echo exceeds that of the second echo; c. measuring the total target strength of an echo from an object, the object being rejected as being a potential underwater acoustic reflector of interest if the target strength is less than a predetermined minimum; d. measuring the acoustic width of an object and comparing that with the acoustic width of known acoustic reflectors, the object being rejected as being potentially an underwater acoustic reflector of interest if the acoustic width is not that of a known underwater acoustic reflector; e. measuring the frequency response of an object, the object being accepted or rejected as being potentially an acoustic reflector of interest if the frequency response corresponds to the known frequency response of such an underwater reflector; and f. measuring the phase response of an object, the object being accepted or rejected as potentially an underwater acoustic reflector of interest if the phase response corresponds to the known phase response of such an underwater acoustic reflector. The target is being rejected as being an acoustic reflector of interest if the measured characteristics do not match the known characteristics of a reflector of interest. The selected steps can be carried out sequentially, concurrently or a mixture of the two. The selected steps may be repeated carried out several times (typically at least three). The results of each repetition are compared before a potential target reflector is selected as being one of interest. The technique allows the location of underwater structures and pipelines to be mapped.
