Radar tracker

(number of frames that satisfies the condision)/(number of total frames) ×100% (11) Table 1 shows the performance of the proposed detection and tracking systems. Tables 2 and 3 show comparisons of the proposed method with other tracking algorithms. Table 1.

The proposed approach outperforms the others in the similar background and severe scale change states. The severe appearance changes, such as skating, show the lowest overlap. However, the proposed algorithm was robust in difficult states such as appearance changes, changes scale, covered object, and similar background. “The Matrioska Tracking Algorithm on LTDT2014 Dataset” [26] and “Locally Orderless…

colonization of the Europeans, tracking was a traditional trade skill in the lives of the Aboriginal people needed to survive in the environment of Australia. Soon after, tracking became a significant role in Aboriginal history because it molded the relationship between the Aboriginals and the white settlers. In the movie adaptation of the novel Follow the Rabbit Proof Fence, the tracker illustrates how perceptions of trackers can transform by witnessing the struggle of the tracker living in…

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…

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…

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…

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…

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…

The surface of Venus was mapped in 1991 by the Magellan expedition, which revealed evidence of extensive volcanic activity on the planet--yet the timing of this volcanic activity remains a mystery. About 80 percent of Venus' surface is covered in volcanic material. Most of the volcanoes are believed to be inactive, yet there is some evidence to suggest more "recently" activity ("recent" in this context meaning within the last 500 million years). There are no lava nor caldera (craters created…

roughness or prevailing geometric shapes from radar imagery (ALOS PALSAR, Radarsat-2). Martelet et al. (2006) used Agglomerative Hierarchical Clustering algorithm to classify airborne gamma-ray spectrometry data in French Guyana and noticed that ferralitic and bauxitic duricrusts display elevated U, Th content relative to K. In West Africa, Grimaud et al. (2015) used the Th/K ratio images to map the extent of the High glacis regolith surface. Regolith landform-maps were derived from gamma-ray…
