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 ...
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 .
The radar (ELM-2001) was installed on the Israeli "Kfir" fighter and went operational in 1974. Practical pulse-Doppler signal processing requires high-power light-weight solid state computing that became available in the early 1970s. The first aircraft to rely completely on its own radar system is the F-4 Phantom.
