Encyclopedia.com. Roger's voice blasted through the intercom from the radar deck. Copyright © 2005 by Houghton Mifflin Harcourt Publishing Company. RADAR is an electromagnetic system for the detection and location of target objects such as aircraft, ships, spacecraft, vehicles, people, and the natural environment which can refl ect a signal back. Radar is an acronym for radio detection and ranging. Pre-war Britain quickly put Watson-Watt's invention to military use and by the end of 1938, primitive RADAR systems dotted the English coast. These stations, able to detect aircraft regardless of ground fogs or clouds , were to play an important role in the detection of approaching Nazi aircraft during World War II. RADAR Full Form : RADAR is an electronic device that uses radio waves to determine the range of a particular object. Scottish physicist and meteorologist Sir Robert Alexander Watson-Watt (1892–1973) successfully used short-wave radio transmissions to detect the direction of approaching thunderstorms. Shortly thereafter, without benefit of a test run, WatsonWatt and Ministry scientists conducted an experiment to test the viability of RADAR. The radar stations would be used to guide interceptors to their targets while the training range would be used to train pilots. The direction of the reflected beam and the time between transmission and reception of a pulse determine the position of the object. Publishers 1998, 2000, 2003, 2005, 2006, 2007, 2009, 2012. Absentee Ballot vs. Mail-In Ballot: Is There A Difference?

Examples: NFL, Not all of the advances, however, were restricted to military use. Top RADAR abbreviation meanings updated September 2020

The use of ASDIC proved pivotal in the British effort to repel damaging attacks by German submarines upon both British warships and merchant ships keeping the island nation supplied with munitions and food. The speakers about the radar room murmured the orders given through all the ship. Within their respective domains, both RADAR and SONAR can operate reliably under a wide variety of adverse conditions to extend human sensing capabilities.

Acoustic location in the air was used even before radar.

While early twentieth century SONAR developments proceeded, another system of remote sensing was developed based upon the improved understanding of the nature and propagation of electromagnetic radiation achieved by Scottish physicist James Clerk Maxwell (1831–1879) during the 19th century. © 2019 Encyclopedia.com | All rights reserved. All people will have heard about Radar but today we are going to give information about its full form. Why Do “Left” And “Right” Mean Liberal And Conservative? Take the quiz to find out! The development of the acoustic transducer that converted electrical energy to sound waves enabled the rapid advances in SONAR design and technology during the last years of the war. SONAR waves (compression waves) travel through water at much slower pace, the speed of sound.

transmitter in much the same way as a smooth mirror can reflect light back in the specular direction.

The ‘Stop Chris Christie’ Movement Begins. Although active SONAR was developed too late to be useful during World War I, the push for its development reaped enormous technological dividends. PSP, HIPAA
