Radar

1a) Air Traffic Control radar surveillance system Air traffic control (ATC) is a service provided by ground-based controllers who direct aircraft on the ground and in the air. The purpose of ATC systems worldwide is to separate aircraft to prevent collisions, to organize and expedite the flow of traffic, and to provide information and other support for pilots when able. b) The operating principles of ATC radar survelliance system Primary Radar Principle: The primary radar unit has a major quality: It works with passive echoes. The transmitted high-frequency impulses are reflected by the target and then received by the same radar unit. Direct cause of the reflected echo is the transmitting impulse sent out by the radar unit. Secondary Radar…

With the current doctrine before a SEAD mission is flown an E-8 JSTAR will fly near the area that the mission will be flown and detect all radar sources that are active (AFFTTP 3-1). This tells the pilots flying the SEAD mission in F-16CJs what type of SAMs are in the area and exactly where the SAMs are. This only works though if the radar is active if the radar is turned off the JSTAR is not able to locate the SAMs. Secondly as the mission is being prosecuted an EC-130H Compass Call flies…

their location being bombed, so thus became the evolution of radar. Radar, developed to see aircraft day or night, worked by using radio waves. The radar worked by shooting out waves through a directional antenna. These waves hit airborne aircraft, and then reflected back to the radar. The incoming waves caused a picture to appear on the radar screen. The picture that appeared on the screen of the aircraft depended on the amount of time it took for the wave signal to get back to headquarters…

of aviation was where most of the development into WW2 military aircraft came about with improved airframe, engine and avionics to serve the war. Compared with WW1, military aviation improved drastically from aircraft designs, but also in military airpower where tactics and strategies for air warfare were developed throughout. Throughout WW2 the aircraft was seen to be a valuable resource for the war, serving many different roles from fighter to bomber. The historical air combat dog fights and…

1. Doppler radar systems provide information about the movement and position of targets. They work by sending a beam of electromagnetic waves at a specific frequency, at a moving object. When a microwave bounces off the object, its wavelength shifts as the object moves (this is known as the Doppler effect). The radar detects the shift and calculates how fast the object is traveling, along with it's location. 2. Polarized sunglasses block reflected light (glare). Since polarized light waves…

ABSTRACT Using remote sensing technology is an effective way to observe and verify the wise and sustainable use of natural resources. With its weather and daylight independency Synthetic Aperture Radar (SAR) data emphasize as particularly suitable for large-scaled monitoring. But the classification of SAR images is more difficult as of multi-spectral images. Because of the microwave’s interaction with the object parameters on the earth surface, like roughness or the complex dielectric…

is to discuss the concept of “teacher radar” for use in class management, class control, and discipline. This article is to help teachers in understanding the concept of teacher radar and use specific strategies for enhancing teacher radar. In addition to comprehend the signals sent by students and know the meanings and ways to proactively react to the signals. To increase class management techniques by understanding and employing early intervention radar techniques and enhancing the student…

In the 1950s, technology was slowly evolving and as it evolved so did the methods used in war and how Americans viewed the government and entertainment. Radar was one of the first advances to contribute to the war, then the development of the Electronic Numerical Integrator and Computer that helped develop the fusion bomb. Next, the first satellite was sent to revolve around the Earth, but it was from the Soviet Union, which resulted in Americans drive to develop Explorer 1. It ultimately…

with its uses here at home with its work with US Customs and Border Patrol as well as NASA. For the US Customs and Border Patrol the primary function is to provide surveillance and reconnaissance along both the US and Mexican border and the US and Canadian border (GCN,2006) (Military.com,2014). These systems are not equipped with armament. I cannot figure out why the Customs and Border Patrol chose to use the MQ-9 Reaper instead of its predecessor the MQ-1 Predator. The only viable option I can…

In the step of object tracking, we estimated the object poses and object information using CamShift and optical flows. Each of the object pose is evaluated and confirmed by object information, comprising several elements such as feature points, descriptors, and object within the sub-window, the expected object pose, and its histogram. The tracked objects are estimated from the credibility for learning of object information, and is described below. In this study, to evaluate the credibility of…
