What is Sonar? - Definition, Uses & Examples Sonar is a way of communicating, navigating, and detecting objects by using sound propagation. For the remainder of this lesson, we will focus on underwater sonar, which is used by submarines and some aquatic animals to perform the previously mentioned tasks.

- Both radar and sonar locate objects from the echo of a signal that is bounced off the object. Radar uses radio waves, which are a type of electromagnetic energy. Sonar uses the echo principle by sending out sound waves underwater or through the human body to locate objects. Sound waves are a type of acoustic energy. Because of the different type of energy used in radar and sonar, each has its own applications.

- Fishfinder Transducers: What You Need to Know. The transducer is an important—and often overlooked—part of your fishfinder. Think of a transducer as your fishfinder’s mouth and ears. It shouts into the depths with its “ping,” and then listens for the echo.

Echolocation : Communication of Marine Mammals, Bats, and Humans Echolocation : Communication of Marine Mammals, Bats, and Humans Equivalent to sonar or radar, echolocation is the production of sound used for communication. Echolocation is the use of ultra-high frequency sounds for navigation and locating prey.

What is an ultrasound? An ultrasound scan is a medical test that uses high-frequency sound waves to capture live images from the inside of your body.The technology is similar to that used by sonar and radar, which help the military detect planes and ships.n ultrasound scan is a medical test that uses high-frequency sound waves to capture live images from the inside of your body.

Garmin ClearVu to debut at SIBS Garmin DownVü is a high-frequency sonar that provides very high-quality representations of structure and fish the boat is passing over. With a finer, concentrated sonar signal scanning a designated area, DownVü provides excellent resolution with great target separation in fresh and saltwater.

- A transducer with a wide cone (50 khz) scans more water and tends to lump things together whether it be fish, stumps, rocks, etc. A narrow cone (200 khz) can detect small details and focuses on structures at a greater depth.The disadvantage here is that it scans a smaller amount of water.re the targets you get displayed as arches on your screen when the Fish I.D. is turned off. Advanced Fish Symbol I.D.™. is part of the Lowrance system which when turned on automatically interprets sonar echos and displays them as fish symbols.

Synthetic-aperture radar Synthetic-aperture radar is a form of radar that is used to create two- or three-dimensional images of objects, such as landscapes. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional beam-scanning radars. SAR is typically mounted on a moving platform, such as an aircraft or spacecraft, and has its origins in an advanced form of side looking airborne radar. The distance the SAR device travels over a target in the time taken for the

- It is SOund NAvigation and Ranging. Sound is used to navigate, and to detect objects in water. Sonography also has other applications.  There are two main types of Sonar syst … ems, active and passive. In active sonar, a pulse of sound is sent out and the operator waits for echoes.

- Radar, which stands for Radio Detection and Ranging, works by transmitting electromagnetic waves that bounce off of a moving object. After the wave is reflected by an object, it changes frequency, and the radar machine interprets the frequency in a calculation of speed.

Definitions &Translations Sonar. Sonar is a technique that uses sound propagation to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels. Two types of technology share the name sonar: passive sonar is essentially listening for the sound made by vessels; active sonar is emitting pulses of sounds and listening for echoes.

Lowrance Electronics Lowrance is a manufacturer of consumer sonar and GPS receivers, as well as digital mapping systems. Headquartered in Tulsa, Oklahoma, Lowrance employs approximately 1,000 people.oon, many boats had more than one sonar unit on board. In 1979, Lowrance introduced the LDD-1800, the world's first sonar unit guaranteed NOT to find fish. The LDD-1800 was one of the first digital depth sounders to be controlled by a tiny computer built inside.

Sonar Acoustic location in air was used before the introduction of radar. Sonar may also be used in air for robot navigation, and SODAR (an upward looking in-air sonar) is used for atmospheric investigations. The term sonar is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic) to extremely high (ultrasonic). The study of underwater sound is known as underwater acoustics or hydroacoustics.

Radar Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar transmits radio waves or microwaves that reflect from any object in their path. A receive radar, which is typically the same system as the transmit radar, receives and processes these reflected waves to determine properties of the object(s).

- What is Ultrasound: Sound is made up of several different frequency waves. The very high frequency range is inaudible to the human ear and is known as ultrasound. Ultrasound was used by the Navy during World War II to detect submarines, and is widely used by fisherman to help find schools of fish.

What is sonar? There are two types of sonar—active and passive. Sonar, short for Sound Navigation and Ranging, is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves. NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the seafloor such as shipwrecks, and map the seafloor itself.

What is sonar advanced protection for norton? Best Answer: Anti virus software has a data base of known virus and other malware. It works at preventing these known bad guys off of your computer. The problem is that brand new virus that have not yet been discovered are not in the data base. This is where Sonar comes in. It watches for suspicious activity on your computer that might indicate a virus. With new threats emerging daily you need the sonar. http://community.norton.com/t5/Norton-Pr...
