A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of the electronics .
Doppler effect. The emitted signal toward the car is reflected back with a variation of frequency that depends on the speed away/toward the radar (160 km/h). This is only a component of the real speed (170 km/h). The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference ...
Doppler on Wheels. DOW 7 on display at the USA Science and Engineering Festival in 2010. Doppler on Wheels (or DOW) is a fleet of X-band and C-band mobile and quickly-deployable truck-borne radars which are the core instrumentation of the Flexible Array of Radars and Mesonets [1] affiliated with the University of Illinois [2] and led by Joshua ...
KYIV (Reuters) -A Ukrainian drone targeted a long-range radar deep inside Russia on Sunday, the second such strike in a week on infrastructure used by Moscow to monitor Ukraine's military ...
The United States military unleashed a wave of attacks targeting radar sites operated by Yemen's Houthi rebels over their assaults on shipping in the crucial Red Sea corridor, authorities said ...
Bistatic radar. Bistatic radar is a radar system comprising a transmitter and receiver that are separated by a distance comparable to the expected target distance. Conversely, a conventional radar in which the transmitter and receiver are co-located is called a monostatic radar. [1] A system containing multiple spatially diverse monostatic or ...
AN/APG-63 radar family. The AN/APG-63 and AN/APG-70 are a family of all-weather multimode radar systems designed by Hughes Aircraft (later Raytheon) for the F-15 Eagle air superiority fighter. These X band pulse-Doppler radar systems are designed for both air-air and air-ground missions; they are able to look up at high-flying targets and down ...
Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. Individual objects can be detected using the Doppler effect , which causes the received signal to have a different frequency from the transmitted signal, allowing it ...
