This acronym stands for 'absent without leave'.  It means that you are tardy.  It means that you are busted!  When you do return you will probably be subject to office hours, or court marshall, or loss of rank and priviledge or perhaps even brig time!  You better have a damn good excuse, like calling on the phone and saying:"Sir, this is Cpl JONES. don't pay the ransom, I bit my way through the ropes and I'm on my way back to base."

Uses the Doppler effect to detect frequency shifts in the transmitted pulse caused by the radial velocity of detected targets.  The echos is processed through a series of RF filters &, based on the amount of frequency shift & angle of approach, the radar can then determine the true target velocity.\n\nMostly used in weather apps.\n\nPS. the speed of light is normally rounded to 3*10^8 meters/sec or 300,000,000 m/s.  Also Doppler is a guy's name.  (Christian Johann Doppler 1803-1853 Austrian physicist)

IT could mean anything. \n\nTry this site http://acronyms.thefreedictionary.com/ETR \nand this http://www.auditmypc.com/acronym/ETR.asp and see which one might fit. It could be anything from Engineering Technical Review\nETR, Engineering Test Reactor, or External Transfer Rate.

WHY DO PEOPLE MENTION THE SPEED OF LIGHT OR FREQUENCY SHIFT OR THE WORD DOPPLER FOR DISTANCE FINDING THEY HAVE NOTHING TO DO WITH RADAR DISTANCE MEASURING.\n\nDOPPLER IS USED TO MEASURE SPEED OF VEHICLES , BASEBALLS ETC. OR DETECT MOTION LIKE THE MOTION IN CLOUDS, TORNADOS, HURRICANES OR THE MOTION OF AIRCRAFT IT IS USED TO DETECT MOVEMENT . \n\nIN DISTANCE MEASURING A MAGNATRON TRANSMITTER TUBE EMITS A SIGNAL DOWN A WAVEGUIDE. A HOLLOW SQUARE COPPER TUBE , IT GOES TO A ELECTRONIC LENS TO A PARABOLIC ANTENNA.  THE SIGNAL TRAVELS THROUGH THE AIR, HITS THE TARGET, BOUNCES OFF, AFTER TRANSMITTING THE RADAR SET GOES INTO RECEIVING,  THE RETURNING SIGNAL HITS THE PARABOLIC ANTENNA IS FOCUSED INTO THE WAVEGUIDE AND TRAVELS BACK TO THE RADAR SET.  THE TIME IT TAKES FOR THE SIGNAL TO RETURN IS HOW FAR THE TARGET IS AWAY FROM THE RADAR ANTENNA!  THE FURTHER AWAY THE LONGER IT TAKES FOR THE SIGNAL TO RETURN.  IT IS NEAR THE SPEED OF LIGHT BUT NOT THE SPEED OF LIGHT!\n\n\nFAR AWAY TARGETS REQUIRE PULSES AT A SLOWER RATE THAN WHEN THE TARGET IS UP CLOSE, UP CLOSE THE PULSE RATE OF THE TRANSMITTER IS QUITE RAPID!  HIGH POWER SEARCH RADAR MIGHT HAVE A PULSE RATE OF 60 PULSES A SECOND FOR LONG RANGE SCAN, WHILE A CLOSE IN RATE CAN RUN OVER 1000 PULSES PER SECOND WHEN AN AIRCRAFT APPROACHES A SHIP TOO CLOSE! \n\nJUST BASED ON THE SPEED THAT RADIO WAVES TRAVEL IN THE ATMOSPHERE, HOW FAR THEY WILL TRAVEL IN SO MANY ZILLIONTHS OF A SECOND!\n\nEARLY RADAR USED ONLY AN OSCILLOSCOPE STRAIGHT LINE WITH A STRAIGHT LINE ON THE LEFT BEING THE TRANSMITTED PULSE AND THE RETURN(S) BEING BUMPS OUT TO THE RIGHT THE DISTANCE BEING THE MEASUREMENT FROM LEFT TO RIGHT! AND THERE WERE MECHANICAL METERS THAT SHOWED WHERE THE ANTENNA WAS AIMED!\n\nTHE RADAR USED IN HAWAII WHEN WE WERE BOMBED BY THE JAPANEESE AT THE BEGINNING OF WW2 WAS THIS TYPE OF DISPLAY!\n\nSO MUCH FOR HISTORY !\n\nHAVE A GOOD DAY.\n\nAPS

Yes it is used in radar scan converters.\nFor more details - http://www.cwcembedded.com/products/0/4/356.html

Acronym is the first letter of each word in a name (FBI = Federal Bureau of Investigation, although I'll bet the acronym most of us are thinking of now is IRS), abbreviation is a shortened version of a word, street = st.

I'm guessing that you are asking because you are looking to purchase.  With that it mind here is some info and I hope it helps!\n\nIn early radar detectors:\nS - Band Radar : operates at 2 - 4 GHz\nX - Band Radar : operates at 10.50-10.55 GHz (Not accurate below 20MPH)\nK - Band Radar : operates at 24.05-24.25 GHz\n\nIn modern radar/ladar detectors:\nKa - Band : operates at 33.4 - 36.0 GHz (has 13 200-MHz channels, can operate in “hop” mode)\nLadar : uses light emitted at 904 nm (typical)\n\nAdvantages of Radar\n*Very flexible - can be used in a number of ways (Stationary mode, Moving mode, Two Directional mode)\n*Beam spread can incorporate many targets\n*Can often select fastest target or best reflection\n*Still very reliable\n\nRadar Disadvantages\n*Time - Radar can take up to 2 seconds to lock on\n*Radar has wide beam spread (50 ft diameter over 200 ft range)\n*Cannot track if deceleration is greater than one mph/second\n*Large targets close to radar can saturate receiver\n*Hand-held modulation can falsify readings\n*More interference sources\n\nLadar Advantages\n*Faster lock-on time (less than 1/3 second)\n*Very narrow beam spread (less than 6 ft over 2000 ft range)\n*Better ability to track decelerating targets\n*Typically mounted, and aimed with optical targeting device\n*Fewer sources of interference\n*Much more difficult to detect\n\nProblems with Ladar\n*Particles (dust, water) in air can limit range\n*Rounded surfaces, the colors black, blue, and violet are poor reflectors\n*Can be difficult to track target\n*Alignment can cause severe error\n*Extreme sunlight can be damaging\n\nConclusions\n*Ladar is, in the correct environment, better suited for speed detection\n*Ladar is not perfect, however\n*There is still room for Radar patrolling\n*Both could be used in concert to achieve maximum detection capabilities

It is just called Mouse, it is not an acronym.\n-----\nHmm well thx for the info and I did try to search again but with no luck and this is what i found.\n\nMinimum Orbital Unmanned Satellite of Earth\nhttp://www.acronymfinder.com/af-query.asp?Acronym=MOUSE&String=exact&p=ol\n\nMOUSE MicroSoft Office User Specialist \nMOUSE Making Opportunities for Upgrading Schools and Education \nMOUSE Minimum Orbital Unmanned Satellite of the Earth \nMOUSE Manually Oscillating Utensil Sonically Engaged \nMOUSE Minimum Orbital Unmanned Satellite Earth\n\nno results in the sote below\nhttp://www.acronyms.com/acronym.php?acronym=M

Wow, I'm usually pretty good at finding these kinds of things, but I was unable to locate what that acronym means.  Sorry!

it is a cyrricllic acronym and stands for Союз Советских Социалистических Республик, which roughly translates to Union of Soviet Socialist Republics or USSR.  So its basically just the Russian version of what we say.

airport or maybe somewhere that they have radar  DUH !!!!
