2. Doppler radar - Wikipedia

   en.wikipedia.org/wiki/Doppler_radar

   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 ...

4. Pulse-Doppler radar - Wikipedia

   en.wikipedia.org/wiki/Pulse-Doppler_radar

   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 .

5. Pulse-Doppler signal processing - Wikipedia

   en.wikipedia.org/wiki/Pulse-Doppler_signal...

   Pulse-Doppler signal processing. Pulse-Doppler signal processing is a radar and CEUS performance enhancement strategy that allows small high-speed objects to be detected in close proximity to large slow moving objects. Detection improvements on the order of 1,000,000:1 are common. Small fast moving objects can be identified close to terrain ...

   en.wikipedia.org/wiki/Channel_5_(web_series)

   Channel 5 (also known as " Channel 5 with Andrew Callaghan " on YouTube) is an American digital media company and web channel, billed as a "digital journalism experience." [2] The show is a spinoff of the group's previous project, All Gas No Brakes, which was itself based on the book of the same name. The channel is hosted by Andrew Callaghan ...

7. Continuous-wave radar - Wikipedia

   en.wikipedia.org/wiki/Continuous-wave_radar

   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 ...
