Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to underwater detection technical field, concretely relates to a kind of multi-beam sonar structure. BACKGROUND
[0002] The measurement of seabed depth is initially mainly to meet the needs of ship navigation and military, such as determining the combat sea area, submarine combat safety guarantee and the safety guarantee of waterway. With the development of marine development, seabed depth data is indispensable information. Multi-beam depth sounding sonar is the most widely used seabed depth measurement device, which can measure the depth data of multiple seabed points in one transmitting and receiving cycle, and has higher resolution than conventional depth sounders. In multi-beam depth sounding sonar, in order to make the beam emitted have directivity, the transducer array of multi-beam acoustic system is basically composed of multiple elements arranged in a straight line, the transmitting transducer converts electrical signals into acoustic signals and transmits them, and the receiving transducer converts the acoustic signals reflected from the seabed and returned to it. If the round-trip time of the acoustic signal from the transducer to the seabed and back to the transducer is measured, the depth corresponding to the irradiated area (footprint or footprint) of the seabed can be calculated by the formula under the condition that the beam tilt angle and the speed of sound in water are known. If a straight-line array is arranged in the forward direction of the vehicle (parallel to the vehicle) to transmit signals, a narrow beam will be formed below the ship, irradiating a narrow strip in the transverse direction. If the array is used to receive the strip echo, it is impossible to determine the position of the echo on the strip, and the specific seabed point depth cannot be measured. CONTENT
