MSC [Meteorological Service of Canada] researchers have already embarked on the development and piloting of a more sophisticated radar system at the King City installation. This next technological enhancement, called dual polarization, is expected to result in far better detection of high impact weather, such as the discri mination of rain from hail and of the various precipitation types in winter storms, and quantitative precipitation estimates that are more reliable.  2, fiche 2, Anglais, - high%20impact%20weather

Les chercheurs du SMC [Service de météorologie du Canada] ont déjà entrepris l'élaboration et l'essai d'un système radar encore plus avancé aux installations radars de King City. Cette amélioration technologique appelée double polarisation devrait aboutir à un bien meilleur niveau de détection des phénomènes météorologiques de fort impact, permettant de distinguer la pluie de la grêle etde divers autres types de précipitation au sein des tempêtes hivernales, et aussi de produire des estimations quantitatives de précipitations plus fiables.  6, fiche 2, Français, - ph%C3%A9nom%C3%A8ne%20m%C3%A9t%C3%A9orologique%20violent

Radar signals bounce off objects in their path, and the radar system detects the echoes of signals that return. Radar can determine a number of properties of a distant object, such as its distance, speed, direction of motion, and shape. Radar can detect objects out of the range of sight and works in all weather conditions, making it a vital and versatile tool for many industries.  2, fiche 3, Anglais, - radar%20signal

Environment Canada developed a Severe Thunderstorm Watch/Warning Program across Canada to ensure the safety and well-being of all Canadians. The purpose of this program is to deliver Severe Thunderstorm and Tornado Watch/Warning Bulletins. These bulletins are designed to provide as much advance warning as possible of hazardous thunderstorm activity and tornadoes. In addition to a continuous surveillance system(e. g., satellite or meteorological radar coverage), the Program relies on weather observations provided by volunteer weather watchers.  1, fiche 5, Anglais, - Severe%20Thunderstorm%20Watch%2FWarning%20Program

LANTIRN consists of a navigation pod and a targeting pod integrated and mounted externally beneath the aircraft. The AN/AAQ-13 navigation pod provides high-speed penetration and precision attack on tactical targets at night and in adverse weather. The naviation pod also contains a terrain-following radar and a fixed infrared sensor, which provides a visual cue and input to the aircraft's flight control system, enabling it to maintain a preselected altitude above the terrain and avoid obstacles. This sensor displays an infrared image of the terrain in front of the aircraft, to the pilot, on a head-up display. The navigation pod enables the pilot to fly along the general contour of the terrain at high speed, using mountains, valleys and the cover of darkness to avoid detection.  2, fiche 7, Anglais, - navigation%20pod

The Next Generation Weather Radar system(NEXRAD) comprises approximately 160 Weather Surveillance Radar-1988 Doppler(WSR-88D) sites throughout the United States and selected overseas locations. This system is a joint effort of the United States Departments of Commerce(DOC), Defense(DOD), and Transportation(DOT). The controlling agencies are the National Weather Service(NWS), Air Weather Service(AWS) and Federal Aviation Administration(FAA), respectively. Level II data are the three meteorological base data quantities : reflectivity, mean radial velocity, and spectrum width. From these quantities, computer processing generates numerous meteorological analysis products known as Level III data. Level II data are recorded at all NWS and most AWS and FAA WSR-88D sites. Level III products are recorded at the 120 NWS sites. The data are sent to the National Climatic Data Center(NCDC) for archiving and dissemination.  3, fiche 10, Anglais, - next%2Dgeneration%20weather%20radar%20system

With SAR the F-15 Strike Eagle becomes an even more capable weapons system which can fly attack missions against ground targets in all weather, such as the notoriously inclement weather of Europe. Using SAR to analyze radar signals reflected from the ground--at distances of over a hundred kilometers--the system can display extremely high resolution images, discerning objects and features down to 10 feet in size.  3, fiche 11, Anglais, - synthetic%20array%20radar
