The Radar The Origin of the Radar: Radar came about during the days of World War II, although people understood what a radars purpose was much sooner than the 1930s. The radar was used in World War II to try to locate aircraft and other ships that were a threat to that country. Radar is a name that was given to it by the United States Navy, and is really an acronym for “Radio Detection And Ranging.” In the early 1900s, the Titanic sailed the deep blue sea for the first and last time. Since the sinking
RADAR RADAR is a term is used to refer to electronic equipment that perceive the presence, course, altitude, and distance of objects by using reflected electromagnetic waves. The term radar is in fact an acronym made up of the words radio detection and ranging (RADAR = RAdio Detection And Ranging). The fundamental basics of RADAR is built upon electromagnetic radiation. RADAR utilises radio waves which is a type of electromagnetic wave on the electromagnetic spectrum. RADAR finds target objects
In the first world war, there was no such thing as a radar, or any form of scanning device, so that the war was only fought by eyes and ears. Whoever heard, or saw the ships first would have had more time to prepare. As far back as June 1932, there had been Post Office Reports about a plane interfering with radio signals, and re-rediating them. Then Sir Robert A. Waston-Watt, A British Electronics Genius, (the man who invented the stereo with only two speakers) came up the idea of RDF, Radio Direction
Research Paper Radar in the Modern World Radar is usually taken for granted in these days of modern technology. Many people do not know how radar is really used, how it works, or why we need it. People are familiar with several uses of radar like police enforcement radar guns and radar that measures how fast a baseball is pitched in a major league game. These are only a few of the many uses radar has to offer. Radar can determine several properties of an object from a distance, such as its position
Police Radar Guns and Jammers Since Radar’s first use in 1937 by Watson-Watt, where they detected the motion of flying objects by calculating the difference in the signals emitted and received, Radars have been used in various occasion (Crochi). After laser was invented, the modern LIDAR system was used in such missions as the Apollo 15 to help draw moon’s map. Apart from its pervasive use in naval and aerial object detection, the modern technologies, based on the principle of Radar’s working mechanism
Radar Detector Radar, which stands for Radio Detection and Ranging, was developed for military purposes. The British and US military used radar to locate ships and airplanes. However, when they were using this technology annoying blips consistently appeared on its screen. It turned out that these blips were raindrops. They saw this hindrance as a wonderful opportunity and in 1957 created the WSR-57 (weather surveillance, 1957), which became the primary radar for the weather service for nearly
Do the Air Force radar systems that are located across the country know as PAVE PAWS, which are capable of detecting ballistic missile attacks and that are used for general space surveillance affect the health of individuals who live in the area surrounding these systems? The United States Air Force has 2 American locations that have radar systems that are used for protection from foreign attacks as well as general surveillance of space. These systems are know as PAVE PAWS. PAVE being a military
Stealth technology is the use of advanced and specially designed material to make an aircraft difficult or even impossible to detect from radars. The goal of stealth technology is to make the aircrafts invisible from radar. A stealth aircrafts are made up of totally flat surface and sharp edges which reflects away all the radar signals at an angle. It also absorbs radar energy. Stealth technology aircrafts are important because it can make strikes without having fear of shot down. For the last decade
technological breakthroughs with satellites and radars that help forecasters predict future weather conditions all around the world. Technologies has advanced throughout the years and are continuing to become more advanced today. Technology has helped scientist understand the most dangerous natural disasters in the world to help protect the public and allow society get to a safe location when the time is necessary. Radar, stands for Radio detection and ranging. Radar transmits microwaves in a focused beam
few different devices that can be used to measure the speed of an object or motion in sports. A radar gun can be used to clock to the speed of objects ranging from large things such as race cars or small things traveling very fast such as baseballs. Although there are different types of radar guns that specialize in each both, both operate with the same principles How Radar Works Basic forms of radar are simple to understand. They can be used to measure many different things such as trains and cars
winds down, the impenetrable mystery of this flight grows even bigger. Now we know the story of MH370. A loaded 777 traveling to Beijing International. A hot night. A calm flight. Not even an hour in the plane goes dark. The transponder and secondary radar tracking are off. Two days later we have confirmed military reports from the Malaysian Air Force that an unknown plane was being tracked across the Malay Peninsula into the Strait of Malacca (Michael Martinez). This means that the plane made a sharp
Introduction In aviation, radar system used to detect aircraft, weather formations and terrain. Radar system uses radio waves to determine the range, altitude, direction and speed of objects. Primary Surveillance Radar (PSR) and Secondary Surveillance Radar (SSR) are installed in ground-based Air Traffic Control (ATC) radar system. PSR is a radar system that detects the positions of the aircraft within the control area and weather conditions. SSR is a radar system that detects the positions of the
You might remember the heroic role that newly-invented radar played in the Second World War. People hailed it then as "Our Miracle Ally". But even in its earliest years, as it was helping win the war, radar proved to be more than an expert enemy locator. Radar technicians, doodling away in their idle moments, found that they could focus a radar beam on a marshmallow and toast it. They also popped popcorn with it. Such was the beginning of microwave cooking. The very same energy that warned the British
The F-35 advancements make it a true multirole fifth generation aircraft; however, with new innovative technologies, there will be challenges in the advancement. Research has revealed deficiencies verses rewards that the F-35 has to offer to the military and that Lockheed Martin is still trying to work out bugs that the program is experiencing. In addition, further testing and extensive budgeting is required for the success in order to deliver a final safe product to all three military branches
Multiple satellite methods exist for remote sensing of rip currents each with their own benefits and drawbacks. Photobathymetry, currents interaction using with Synthetic Aperture Radars (SARs), wave refraction, and wave kinematics bathymetry (WKB) are current technologies that are used most often due to the current satellite knowledge. Each of these techniques can be applied using low orbit satellites that are already currently orbiting Earth. All techniques aside from WKB have been tested as satellites

The Lockheed Martin F-22a Raptor fighter jet is the pinnacle of modern stealth technology. Featuring the absolute latest in radar absorbent covering and aircraft design, this plane not only defies, but also laughs at enemy attempts to spot it, showing up as a blip the same size as a marble would on radar. Throughout the ages, it has not been he with the bigger stick who won the war, but he with the stick that could not be seen. Stealth technology and camouflage have been an integral part of warfare
racial profiling but they are far from the truth. This is wrong because I did a test with a white friend of mine. We used my mother’s Jeep and we drove through a hot spot in Riverdale Park, Maryland. First we drove around until we found a cop doing radar check on passing cars. Now we decided to see if they would pull over my white friend so he drove by the cop ten times in 10 minutes and he was driving very slow as if he was lost. The cop never paid him any mind. Keep in mind that we are videotaping
Doppler radar Meteorologists and weather analysts use the Doppler Effect to read weather events. In this case, the fixed transmitter is located at a weather station and the moving object being studied is a storm system. This is what happens: 1. Radio waves are emitted from the transmitter at the weather station at a specific frequency. 2. The waves are large enough to interact with clouds and other atmospheric objects. The waves strike the atmospheric objects and bounce back toward the receiver at
police. How do they know how fast we are going? Speed determination is accomplished in two basic ways. First, the least sophisticated method is dependent upon an officer's ability to guess your speed. Second, either some electronic method using radar or laser instrumentation authenticates that officer's guess. As you will see, their guesses are usually right on target. What does this mean for you? Usually a speeding ticket or if your infraction isn't a flagrant disregard for safety, a friendly
