Hand-held imaging sonar and imaging method thereof

Abstract

The invention provides hand-held imaging sonar and an imaging method thereof. The hand-held imaging sonar is characterized by comprising a watertight electronic tank, a display box, a battery box, andthe like, wherein a transducer group is mounted on the front-end surface of the watertight electronic tank and comprises a transmitting transducer array and a receiving transducer array which are mounted on a front-end cover of the electronic tank and are connected with an electronic system mounted in the electronic tank; the rear end surface of the electronic tank is provided with two watertightsockets which are used for connecting the display box and the battery box by a watertight cable; a handle for holding the sonar is mounted on a rear end cover of the electronic tank; the battery boxcan be carried by a driver together with other accompanied equipment; and the watertight electronic tank and the display box are fixedly connected so as to be held and operated by the driver. The hand-held imaging sonar helps the driver to observe muddy underwater environment and search objects, enables imaging to have real-time property and achieves underwater imaging and display.

Description

technical field [0001] The invention belongs to the field of underwater acoustic engineering, in particular to a handheld imaging sonar capable of imaging and displaying underwater and an imaging method thereof. Background technique [0002] The rivers in our country generally have the characteristics of high sediment content, so the water quality is turbid, and the seawater near the sea also has the same characteristics. In such water quality conditions, imaging conditions are very harsh. At present, when divers work underwater, they usually need to carry a high-power light source and use it to illuminate the targets ahead. Therefore, the observation and perception range of divers is the human visual range under optical conditions, usually within the range of meters. In underwater operations, there are also optical imaging equipment, such as micro-imaging systems, but even in the case of good water quality, the imaging distance of optical equipment underwater can only be m...
