摘要： A marine sonar display device comprises a display, a memory element, and a processing element. The processing element is configured to transmit a transmit electronic signal to a frequency steered sonar element that transmits an array of sonar beams into a body of water in a first direction towards the front of the marine vessel forming a first sonar wedge and a second array of sonar beams into a body of water in a second direction directly below the marine vessel forming a second sonar wedge, receive a receive electronic signal from the frequency steered sonar element, generate an array of sonar image slices, identify a gap in an underwater area between the first sonar wedge and the second sonar wedge, and control the display to visually present the array of sonar image slices in near real time and a sonar image slice in the gap.

摘要： Many different types of systems are utilized and tasks are performed in a marine environment. The present invention provides various configurations of castable devices that can be operated and/or controlled for such systems or tasks. One or more castable devices can be integrated with a transducer assembly, such as a phased array, that emits sonar beams and receives sonar returns from the underwater environment. Processing circuitry may receive the sonar returns, process the sonar returns, generate an image, and transmit the image to a display.

摘要： An underwater information visualization device, which is installed on a moving body such as a ship traveling near a water surface and visualizes and displays information about fish in the water and the seabed using an ultrasonic wave, includes circuitry that generates a pseudo noise sequence signal and a modulation circuit that modulates a carrier signal to form a transmission signal, emits a transmission signal as an ultrasonic wave into the water, receives an echo of an ultrasonic wave, determines an echo corresponding to a transmission signal by subjecting the echo to correlation processing with a pseudo noise sequence signal, displays an output signal. The display simultaneously displays multiple reception signals on a screen, and a period of transmission signals is (2D/Vu) or less when an underwater sonic wave speed is Vu and a distance to the seabed is D.
