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 ...

WRAL-TV began broadcasting on December 15, 1956. Among the first programs aired was the movie Miracle on 34th Street.A. J. Fletcher's Capitol Broadcasting Company, which first licensed WRAL Radio (AM 1240, now WPJL) in 1938, won the TV license in an upset over the much larger Durham Life Insurance Company, then-owners of radio station WPTF.
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.
