摘要： A method for pre-determining an underwater objects GPS position using a rotatable scan sonar unit linked to a boat, 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 sonar transducer and mounted on a 360 degree movable mechanism such as a trolling motor unit, or phased array of transducers and a compass to provide heading information and formulates the objects position based on the distance and heading of the object in relation to the boats current GPS position.

摘要： Sonar devices for detecting underwater objects are provided whereby a set of angled ultrasound transducers are employed to sense ultrasound signals from a plurality of different spatial regions. The angled ultrasound transducers may include a first pair of side-viewing ultrasound transducers and a second pair of ultrasound transducers configured for interrogating forward and reverse directions. The ultrasound signals from the set of angled ultrasound transducers may be processed to identify the presence of underwater objects in each spatial region, and the resulting identified underwater objects may be displayed, on a per-region basis, on a user interface. The ultrasound signals may additionally or alternatively be processed to generate a topographical model of the bed surface, and to generate a topographical surface image based on the three-dimensional topographical model. The topographical surface image may be displayed as a fly-over animation.

摘要： A forward scanning sonar system including at least a sonar transducer and a support structure having the at least a sonar transducer mounted thereto, the at least a sonar transducer being configured such that, while during scanning operation the sonar transducer is moved along a forward moving direction, a fan-shaped beam of the sonar transducer is forming a plane oriented forwardly downwardly such that the fan-shaped beam forms a scan line oriented at a scan angle to the forward moving direction with the scan angle being greater than 0 and smaller than π/2 and such that the scan line intersects the forward direction at a point ahead of the sonar transducer.

摘要： System and methods for compensating a depth signal for a depth finder of a boat. In one embodiment, a compensation system is implemented between the depth finder and a transducer mounted on the boat. The compensation system receives a depth signal (i.e., a plurality of electrical impulses) from the transducer that directs sound waves toward the bottom of a body of water. The compensation system also monitors a change in elevation of the transducer, such as due to waves rocking the boat. The compensation system then compensates the depth signal based on the change in elevation, and provides the compensated depth signal to the depth finder.

摘要： An apparatus, method, and computer-readable medium for high ping rate depth sounding. The apparatus may cause transmission of a first sonar beam having a first frequency and transmission of a second sonar beam having a second frequency with a transducer assembly. The transducer assembly maybe configured to transmit the first sonar beam and the second sonar beam into the underwater environment. The apparatus may receive sonar return data from the transducer assembly beginning either simultaneously with transmission of the first sonar beam or prior to transmission of the second sonar beam. The apparatus may further determine, based on sonar return data acquired after transmission of both the first sonar beam and the second sonar beam, that the sonar return data corresponds to the first sonar beam by determining that the sonar return data comprises the first frequency.

摘要： Techniques are disclosed for systems and methods to provide sonar systems for mobile structures. A sonar system includes a sonar transducer assembly including a sonar transducer, a sonar receiver configured to receive acoustic returns from the sonar transducer and convert the acoustic returns into arrays of time differentiated sonar data samples, and a logic device adapted to communicate with the sonar receiver. The logic device is configured to receive the arrays of the time differentiated sonar data samples from the sonar receiver and process the received arrays to enhance the time differentiated sonar data samples substantially without enhancing sonar artifacts in the time differentiated sonar data samples Processed sonar data and/or resulting imagery may be displayed to a user and/or used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the sonar transducer assembly and/or a mobile structure.

摘要： Provided are a sonar system and transducer assembly for producing a 3D image of an underwater environment. The sonar system may include a housing mountable to a watercraft having a transmit transducer that may transmit sonar pulses into the water. The system may include at least one sidescan transducer array in the housing that receives first and second sonar returns with first and second transducer elements and converts the first and second returns into first and second sonar return data. A sonar signal processor may then generate a 3D mesh data using the first and second sonar return data and at least a predetermined distance between the transducer elements. An associated method of using the sonar system is also provided.
