Sonar, or Sound Navigation and Ranging, started out as a military application during the 1st World War. In fact, it was originally referred to as ASDICS, or Anti-Submarine. Detection Investigation Committee. It was devised to detect enemy submarines and ultimately destroy them. It wasn't until 1953, following a deal with.
5 May 2010 Sound navigation and ranging (SONAR) systems have many similarities to radar and electro-optical systems. The operation of sonar is based on the propagation of waves between a target and a receiver. Sonar differs fundamentally from radar and electro-optical systems because the energy observed by
2. What is Sound? Sound is a mechanical wave motion propagating in an elastic medium. Associated with this wave motion are changes in the local pressure and density. Sonar, an acronym for SOund NAvigation and Ranging, uses sound energy (generally underwater) to transmit information.
Sidescan Sonar extends the beam of sound laterally, in a fan, mapping a swath across the seafloor. www.fugro.com. General Terms and Definitions. Recall: SONAR == SOund Navigation And Ranging i.e., What direction is the target and how far is it • What direction is the target? Straight down, out to the side, or somewhere
applications. It also discusses the way we see fish and harmful effects of sonar systems while providing a brief description of the factors that affect the performance of a good sonar system. How SONAR works. The word "sonar" is an abbreviation for "SOund, NAvigation, and Ranging". This is a technology that was developed
This paper gives a short introduction to underwater sound and the principle of sonar. In addition, the paper describes the use of sonar in three different applications: fish finding; mapping of the seafloor and imaging of the seafloor. I. INTRODUCTION. SONAR is the acronym for SOund Navigation And. Ranging. Sonar
SONAR (Sound Navigation and Ranging). Sonar is a technique for impinging pulse (the angle at which the sound pulse strikes the new medium), and the roughness of the new medium's surface.

OBJECTIVE: Provide students a basic understanding of how sonar (SOund NAvigation and Ranging) is used to map the ocean floor. Students use a simple calculation to determine the depth of the ocean floor at 15 points from Miami Beach eastward to the wreck of the SS Sapona in the Bahama Islands. This is a total
