"The following paper will explore the impact of radar upon the Second World War and its outcome. To be more specific, the next several pages will look at how the steady development of radar facilitated (prompted) collaboration and closer communication between British and American scientists, spared Britain during the 1940 Battle of Britain (a period in time when it seemed as though the ultimate success of the Nazis was just a matter of time), immensely advantaged the Allies as they struggled to secure mastery over the Atlantic and its shipping lanes, aided the Americans as they wrestled for control of the Pacific with the Japanese..."

Abstract
The paper begins by explaining basically what radar is and for what it's used. Then the paper recounts the history of radar's development, both theoretically and practically. From the history of radar the paper returns to the question of how it works, but analyzes the physics in depth, and breaks down the operation of each of a radar system's components. The paper finishes with a review of modern applications of different types of radar systems.

From the Paper
"Parallel developments occurred in a number of countries. The highest frequency at which then-current technology allowed substantial power to be generated was about 30MHz, the top end of the HF band. UK radar development proceeded rapidly from 1935 so that by 1937 the first operational (HF) radars of the Chain Home series were demonstrated. These frequencies were in place at the outbreak of World War II and played a decisive role in the air defence of Britain during the War. Wartime radar development quickly moved on to shorter wavelengths as devices were developed to allow generation and control of the power, but the Chain Home radars remained in service, as originally installed. The Chain Home radars, operating between 25 to 30MHz, on occasions indicated returns from extreme ranges, due to ionospheric reflection beyond the horizon. But they were intended as line-of-sight radars and long-range returns from the distant ground via an ionospheric reflection were generally only a source of confusion. During the War some attempts were made to use the ionospherically propagated signal for long range detections of convoys but no success was achieved (or could be expected) and tests were dropped."

Abstract
This report is designed to introduce the future officer to traffic radar. It explains to the future police officer the kind of radar units he/she may encounter on a job, how they work, public opinion of them and touches on the potential health hazards that radar units can present.

From the Paper
"Since its introduction to traffic law enforcement in 1948, radar has been an integral component of vehicular speed measurement. Each year hundreds of thousands of dollars are collected in courts throughout the nation from motorists whose speed was monitored with the aid of this electronic instrument. Today, radars overall efficiency and effectiveness have been greatly enhanced. In spite of its great improvements, radar is currently being scrutinized, questioned, and challenged, not only for its reliability but also for the quality of operator training. "

Abstract
This paper explains that, for innumerable years, the only way to develop effectively an archaeology site was by the laborious and area-disturbing digging of trial sites; however, today, computer technology presents the ability to see what the terrain looks like beneath the surface. Next, the author describes the development of ground penetrating radar (GPR) devices, which are classified as remote sensing tools. The paper illustrates its application at known archeology sites, such as Memphis in Egypt, and its use to examine construction sites before excavation to be sure that valuable archeological information is not destroyed.

From the Paper
"These continuous readings display a picture of the earth below its surface, on an imaging screen and can also be recorded and or copied to provide a physical reference that coincides with the structural grid used to delineate the area where the radar is being employed. The grid itself is often associated with GPS location tracking but in the past has been associated with other measures, such as existing landmarks. Above (right) is a photograph of an early GPR device, being utilized on a dig site in Egypt to determine what might exist in an area surrounding a pyramid."

Abstract
The paper analyzes the radar cameras and red light cameras on the road. The paper relates how since the 1990s these technological methods for catching motorists in the act of speeding or running red lights has been touted by advocates as a powerful weapon for improving the safety of the roads. The paper explains, however, that critics call the technology Orwellian and they claim that the cameras have been employed primarily to increase revenue both for individual cities as well as the vendors who provide this technology. This paper researches the general pros and cons of the issue, examining some pertinent legislation.

"The purpose of this paper is to examine the radar cameras and red light cameras. Since the 1990s these technological methods for catching motorists in the act of speeding or running red lights has been touted by advocates as a powerful weapon for improving the safety of the roads. However, critics call the technology Orwellian and claim that the cameras have been employed primarily to increase revenue both for individual cities as well as the vendors who provide this technology. This paper will research the general pros and cons of the issue, examining some pertinent legislation as well as the major claims of both sides of the matter. In the end, however, it is and will be my position that photo radar and red light cameras are effective only at lining the city coffers."

Abstract
The paper looks at the role of observation in hurricane forecasting by satellites ships, buoys, reconnaissance aircraft, radiosondes and radar. The paper then relates that scientists use complicated computer models to chart the storm's intensity and progress and issue warnings to the public. The paper discusses the prediction models available and shows how it is extremely difficult to forecast hurricanes totally correctly throughout the hurricane season, since there are still too many variables in gathering and analyzing the data that is available.

From the Paper
"Observation is the first element of hurricane forecasting, and it includes several methods of observing and tracking hurricanes and tropical storms that could develop into hurricanes. Observation begins when the predicted storms are far away from land and still far out to sea (all hurricanes form over oceans). The first method of observation is satellites, or the Geostationary Operational Environmental Satellites (GOES). These satellites are used to provide a wide variety of data on the forming hurricanes, such as "location, size, movement, and intensity of a storm, and analyze its surrounding environment" ("Observations"). In addition, the satellites emit radiation that reflects from the atmosphere, which allows the satellite to measure moisture, winds, atmospheric temperature, and cloud cover of the storm. All of this data is transmitted to the NHC, where it is analyzed."

Abstract
The paper reveals that tornadoes are one of nature's most powerful forces. The writer explores the strengths of a tornado, the type of damage it does and the steps that can be taken to warn communities of its possible arrival. The paper discusses the Doppler radar system that can detect a tornado while it is still in the sky, the tornado siren system and trained human storm chasers and spotters. The paper explains that one of the problems with tornadoes is their unpredictability, but as emergency management teams nation wide continue to improve, the public will become increasingly safer.

Conclusion

From the Paper
"Out of all the natural disasters that can occur, tornadoes are often considered the most damaging and the most dangerous. While earthquakes are unpredictable, they have not developed a history in the United States of frequent occurrence or many deaths. Hurricanes, with the exception of Katrina usually provide enough advanced warning that the emergency management coordinators can provide notice to evacuate. Tornadoes, however, often strike with little or no warning and they can come in "swarms" during optimum weather conditions(Gugliotta, 2003)."

Abstract
This paper looks at the B-2 Stealth Bomber program which is funded by Congress and supported by different administrations. The B-2 Bomber is noted for its use of stealth technology, which makes it virtually invisible to radar as a means of detecting its presence. It examines how critics have pointed out a number of flaws in this technology and in the entire program together with a report from the General Accounting Office in 1998 was especially critical and generated a response from the Air Force in an attempt to counter the critics. It shows how an evaluation of the project suggests that while the technology could be useful, it is not yet sufficiently developed to be utilized at the level the Air Force would like and the costs would support.

From the Paper
"The B-2 bomber might be useful in certain situations, but the number that are already in operation could suffice for such operations. The Pentagon originally stated that it needed only 20 B-2s for all purposes, and it has more than that now. The manufacturer claims it can make the bombers less expensively, but this does not mean they are needed (Thompson 41). While high cost might be a consideration in determining whether such a system is needed or not, the primary rationales should be need and effectiveness. In the case of the B-2, not only is it expensive, it is also probably not needed and does not work as advertised in any case. Given that there is no evidence at all that the bombers can be fixed or that they will suddenly become needed, the program should be ended. Even if there were such evidence, the costs might not be justified by the small return that would be achieved."

Abstract
This essay is an examination of the shoot-down of KAL flight 007 in 1982. The author puts forth the idea that KAL 007 was used by the Reagan administration to test Soviet radar capabilities and that once the plane was shot down by Soviet fighters, the disaster was covered up.

From the Paper
"Official reports claimed the 747 was shot down, crashed into the ocean, and disappeared. No large debris from the crash was every recovered, however. The Soviets claimed they had found the plane in 300 feet of water off an island near Japan , but never removed the wreckage. Only tiny pieces of the plane and small body parts were ever found. The small sizes of the pieces recovered indicate depressurization of the cabin, and that the plane was not destroyed in the air."
