WebDec 8, 2024 · The ordinary radar is also called time-of-flight radar. Doppler Radar. Different from ordinary radar, Doppler radar could also be used for measuring the the relative velocity between the radar and the target object $\Delta v$. Doppler Effect. Let’s consider the Doppler effect in the simplest 1D scenario. A radar altimeter measures altitude more directly, using the time taken for a radio signal to reflect from the surface back to the aircraft. Alternatively, Frequency Modulated Continuous-wave radar can be used. The greater the frequency shift the further the distance travelled. This method can achieve much better accuracy than the pulsed radar for the same outlay and radar altimeters that u… multiply prevalence by population
