HYDROACOUSTIC SYSTEM FOR IMAGING UNDERWATER SPACE Russian patent published in 2012 - IPC G01S15/89 

FIELD: physics.

SUBSTANCE: hydroacoustic system for imaging underwater space has antenna units for the portside and the starboard 1 and 1', receiving amplifiers 2 and 2', analogue-to-digital converters 3 and 3', power amplifiers 4 and 4', a multi-beam echo sounder antenna 5, receiving amplifier units 6, analogue-to-digital converter units 7, a power amplifier unit 8, a roll measuring device 9, a depth measuring device 10, a module for generating, receiving and packing signals 11, an interface unit 12, a navigation system 13 and an on-board computer 14. The invention provides a continuous band for scanning the bottom owing to that the invisibility band of the antennae of the portside and the starboard overlaps with the multi-beam echo sounder; formation of the bottom relief in real time, higher accuracy and reliability of imaging the relief due to high accuracy and reliability of eliminating ambiguity when calculating phase shift on antennae.

EFFECT: providing a continuous band for scanning the bottom and formation of the bottom relief in real time.
