Doppler Radar Basics Pulsed radar detects a phase shift between the transmitted and returned signals a target is sampled with many pulses - Spectral Width Doppler - infers a wind field from radial velocity similar limitations as conventional radar

Doppler Shift Simulation

Doppler Frequency Frequency for sound is about 10,000 Hz For 50 kt motion of train and using velocity= frequency change x wave length Frequency change is about 800 Hz or 8 percent… detectable by human ear.

Radar beam Frequency 10**9 Hz Change in frequency 10**-5 percent not detectable by any electronics. Equations for Doppler frequency shift different for sound than E-M
