What is sonar and which one is sonar

Sonar is a thing that can be used for a variety of purposes.

Sonar is also called sonar. In fact, sonar represents a physical quantity, and in physics, "acoustic admittance" is used to indicate the ability of a substance to allow sound to pass through, and the English is acousticsusceptance, which has long been named, so other concepts can no longer be expressed by this term. The word sonar refers to a kind of acoustic wave detection instrument and a kind of underwater acoustic equipment, and the two should not be confused.

In 1996, the "Physics Terminology" has made it clear that "sonar" is a canonical word, but in the early days, most dictionaries translated sonar as "sonar", so many dictionaries still translate it as "sonar".

"Sonar" is the national standard, and "sonar" is the military standard, and the names are different.

Sonar is an acoustic detection device, and active sonar was first used in the United Kingdom, although the British called this device ASDIC (Submarine Probe). The sonar device is generally composed of three parts: the base array, the electronic cabinet and the auxiliary equipment. The base array is composed of hydroacoustic transducers arranged in a certain geometric shape, and its shape is usually spherical, cylindrical, flat or line row.

There are receiving base arrays, transmitter arrays, or transmitting and receiving integrated base arrays. Electronic cabinets generally have subsystems such as transmitting, receiving, displaying, and controlling. The auxiliary filial piety equipment includes power supply equipment, connecting cables, underwater junction boxes and amplifiers, lifting, rotating, brother search pitching, retracting, dragging, hoisting, putting and other devices that are matched with the transmission control of the sonar base array, as well as sonar shrouds.

Important devices in sonar:

Transducer is an important device in sonar, which is a device that converts sound energy with other forms of energy such as mechanical energy, electrical energy, magnetic energy, etc. It has two uses: one is to emit sound waves underwater, called the "Emission Changer", which is equivalent to a speaker in the air; The second is to receive sound waves underwater, which is called a "receiving transducer", which is equivalent to a microphone in the air (commonly known as "earpiece").

Transducers are often used to transmit and receive sound waves at the same time, and transducers specially designed for reception are also called "hydrophones". Transducers work on the principle of piezoelectric or magnetostrictive effect, which uses the piezoelectric or magnetostrictive effect of certain materials to expand and contract under the action of an electric or magnetic field.

Summary. Hello, I'm glad to answer for you: kiss, sonar; Sonar generally refers to sonar, which is the Chinese transliteration of the English abbreviation "sonar", which is the technology of navigation and ranging through electroacoustic conversion and information processing using the propagation and reflection characteristics of sound waves in water, and also refers to the electronic equipment that uses this technology to detect and communicate underwater targets.

Hello, Zaola is happy to answer for you: kiss, sonar; Sonar generally refers to sonar, which is the Chinese transliteration of the English abbreviation "sonar", which is the use of sound waves in the water to propagate and reflect the characteristics of jujubes, through electroacoustic conversion and information processing for navigation and ranging technology, and also refers to the use of this technology to detect and communicate electronic equipment for underwater targets.

Addendum: Sonar and sonar mean the same thing. Sonar technology is more than 100 years old, and it was invented in 1906 by Lewis Nixon of the British Navy.

His first sonar mold was a passive listening device used to detect coded oak icebergs. This technology began to be applied to the battlefield in the First World War, used to detect submarines hidden underwater, these sonars can only be passively heard, belonging to passive sonar, or called "hydrophones", and later people invented active sonar.
