Doppler spread

In general, the width of the Doppler spectrum, measured in units of either frequency or velocity.

Quantitatively, the Doppler spread is usually defined as the standard deviation of the Doppler velocity about its mean value, regarding the velocity as a continuously distributed random variable with a probability density function equal to the normalized Doppler spectrum.
See Doppler spectral moments; Doppler spectral broadening.
