Convert Doppler shift to speed
radvel = dop2speed(Doppler_shift,wavelength)
the radial velocity in meters per second. This value corresponds to
the one-way Doppler shift,
radvel = dop2speed(
wavelength, in meters.
Calculate the radial velocity of an automobile based on the Doppler shift of a continuous-wave radar. The radar carrier frequency is 24.15 GHz. Assume a doppler shift of 2.880 kHz.
f0 = 24.15e9; lambda = physconst('LightSpeed')/f0; dopshift = 2.880e3; radvel = dop2speed(dopshift,lambda)
radvel = 35.7516
The radial velocity is approximately 35.75 meters per second or 80 miles/hour.
The radial velocity of a source relative to a receiver can be computed from the one-way Doppler shift:
