摘要： A method for pre-determining an underwater objects GPS position using a forward scan sonar unit linked to a boat trolling motor, magnetic compass and GPS receiver. This system determines the underwater objects GPS position using the objects distance, compass heading and a GPS receiver/sonar on a boat. This system will provide real time longitude and latitude positions of underwater objects seen with sonar at a distance from a boat, and will allow for precise autopilot navigation or fixed position fishing. The system can also be used to correct for GPS errors when using previously stored waypoints positions of an object. The computer determines an objects underwater GPS position using a forward scan sonar transducer and compass mounted on a 360 degree movable mechanism such as a trolling motor unit, and formulates the objects position based on the distance and heading of the object in relation to the boats current GPS position.

摘要： A downscan imaging sonar utilizes a linear transducer element to provide improved images of the sea floor and other objects in the water column beneath a vessel. A transducer array may include a plurality of transducer elements and each one of the plurality of transducer elements may include a substantially rectangular shape configured to produce a sonar beam having a beamwidth in a direction parallel to longitudinal length of the transducer elements that is significantly less than a beamwidth of the sonar beam in a direction perpendicular to the longitudinal length of the transducer elements. The plurality of transducer elements may be positioned such that longitudinal lengths of at least two of the plurality of transducer elements are parallel to each other. The plurality of transducer elements may also include at least a first linear transducer element, a second linear transducer element and a third linear transducer element. The first linear transducer element may be positioned within the housing to project sonar pulses from a first side of the housing in a direction substantially perpendicular to a centerline of the housing. The second linear transducer element may be positioned within the housing to lie in a plane with the first linear transducer element and project sonar pulses from a second side of the housing that is substantially opposite of the first side. The third linear transducer element may be positioned within the housing to project sonar pulses in a direction substantially perpendicular to the plane.

摘要： An apparatus for performing beam pattern measurements for a side-scanning nar. The apparatus consists of a vertically mounted guide affixed to one end of a test pool and a vertically fixed mounting means affixed to the opposite end of the pool, the guide and mounting means orthogonal to each other. A carriage to which the transducer under test is attached is movably secured to travel up and down the guide. A gear motor having a takeup reel winds and unwinds an attached cable, the other end of which connects to the carriage, producing its up and town travel. The motor connects via a motor controller and position cable to a motor controller at a remote instrumentation facility. A position sensing device slaved to the carriage cable sends carriage position information to the facility for motor control. The array is secured immobile to the vertically fixed mounting means. The vertically fixed mounting means may be arranged to permit horizontal travel in the direction of the vertically mounted guide for range adjustment.

摘要： A sonar system is provided for identifying a foreign object includes a technique for providing a two dimensional array of pixels, each one of the pixels representing the intensity of a signal at a predetermined range position and a predetermined cross-range position from a reference position and quantizing the intensity of each one of the pixels into one of a plurality of levels. The technique further includes comparing a distribution of the levels of pixels over a range scan at a cross-range position with the distribution of levels of pixels over a range scan at a different cross-range position to identify the existence of a foreign object. With such an arrangement a sonar system is provided that can automatically detect the existence of a foreign object such as a mine.

摘要： Ocean bottom mapping is carried out by projecting a sonic pulse in the formf a fan-shaped beam from a vessel toward the ocean floor, receiving echoes by an array of sonic detectors extending athwartship, repeatedly taking instantaneous, simultaneous, snapshot-like samples of all of the detectors in the array, and, by means of a digital computer, applying a beam-forming transform, such as a Fast Fourier Transform, to the samples, thereby producing a spectrum of amplitudes versus angles. The directions of the floor areas from which the snapshot data emanate are determined from refinement of the peaks in the spectrum of amplitudes, and the distances of the same floor areas from the vessel are determined by the time interval between the pulse and the sample. A bottom profile is constructed from the directions and distances so determined. Two alternative techniques for refining and interpreting spectrum data are described.

摘要： A method and apparatus steers the returning beams of a receiver in a swath bathymetric system to an actual target based on prior steering angle information for the target and using an algorithm which demonstrates a linear relationship between the phase of the return beam and the steering angle therefor. The receiver comprises a plurality of transducing elements which each emit a signal. The array is divided into two groups of elements which are processed and combined to form beams for each group which are steered to the known steering angle for the target. Beams are then steered to a slightly offset angle to produce an offset beam. Using an equation to define each return beam according to phase and error between prior known and actual steering angles for the target, the error value can be reduced to zero to provide an accurate measurement of the actual steering angle for the target.
