a measuring instrument that sends out an acoustic pulse in water and measures distances in terms of the time for the echo of the pulse to return; sonar is an acronym for sound navigation ranging; asdic is an acronym for anti-submarine detection investigation committee
It must be noted, that when a sound takes 10 s to come back to you when using SONAR, the time taken is actually 5.0 s for one way. Thus when asked to find the depth of a ocean, etc. the time taken which must be used is that of one way.
A system for detecting obstacles by emitting sound and intercepting and interpreting echoes that bounce back. It is used by bats and also by oilbirds and some swiftlets when they fly in the darkness of caves.
An acronym for SOund NAvigation and Ranging. It includes any system that uses underwater sound, or acoustics, for observations and communications. There are two broad types of sonar: Passive sonar detects the sound created by an object (source) in the water. This is a one-way transmission of sound waves traveling through the water from the source to the receiver; and Active sonar detects objects by creating a sound pulse, or ping, that transmits through the water and reflects off the target, returning in the form of an echo. This is a two-way transmission (source to reflector to receiver) and is a form of echolocation.
sound navigation and ranging. A device that is used primarily for the detection and location of underwater objects by reflecting acoustic waves from them, or by the interception of acoustic waves from an underwater, surface, or above-surface acoustic source.
Detection equipment used to detect and track submarines. A distinct pinging sound was emitted from a transmitter/receiver attached to the hull. Sonarmen were sometimes referred to as "ping-jockeys". Short for "true". Used when noting direction ("bearing") of an object (such as the ship's course, another ship, or enemy plane) in degrees
A system using transmitted and reflected underwater sound waves to detect and locate submerged objects or measure the distance to the floor of a body of water. This technology is used in Garmin fishfinders and sounder products.
Sonar (SOund NAvigation and Ranging) is a simple way to detect wrecks. It uses sound pulses/echoes, it is inexpensive and can be fitted in small boats. Modern systems can be combined with GPS. A split-screen function allows for detail studies while keeping the overview. Some sonars are sediment-penetrating, revealing objects below the seabottom. Image from SMAS of a wreck.
Acronym for ' So und avigation nd anging'. Sonar works by sending out sound waves in water and measuring distance by the time it takes for the sound wave to reach and bounce off (echo) an object (or the bottom) and return back to the sender. Originally developed for detecting submarines (the famous ping).
an acronym for sound navigation and ranging equipment. SONAR systems use sound waves to detect underwater objects by listening to the returning echoes. The distance to the object or the seafloor can be calculated by measuring the time between when the signal is sent out and when the reflected sound, or echo, is received.
Word is derived from "sound navigation and ranging." It describes a devise that transmits frequency sound waves in water and registers the vibrations reflected back from an object. It is used in detecting objects such as submarines, locating schools of fish, or determining water depth.
Whales use sonar to sense objects. In sonar (echolocation), a high-pitched sound (usually clicks) is sent out by the whale. The sound bounces off the object and some returns to the whale. The whale interprets this returning echo to determine the object's shape, direction, distance, and texture.
SONAR (SOund Navigation And Ranging) — or sonar — is a technique that uses sound propagation under water (primarily) to navigate, communicate or to detect other vessels. There are two kinds of sonar — active and passive. Sonar may be used as a means of acoustic location.
Sonar is a desktop application to send SMS text messages to Cellular Phones in Argentina. It works with cell phones of any Company: Personal, Movicom, CTI, Nextel and Unifon. It has a MSN like interface , and is written in Java/SWT
Sonar is the name of a fictional character from the Transformers toyline. He is a Maximal and takes the beast form of a bat. He is a clone, created and altered by the Predacon Megatron, of Onyx Primal.
sonar is a network reconnaissance utility. It runs all its scans from plugins. The currently supported plugins are an ICMP scan and an ACK scan which can see if hosts that don't respond to ICMP are online. With the ability to create your own plugins, sonar is becoming the most extensible security scanner available.
