Medical Definition of Doppler broadening
1.
Frequency spreading which causes broadening of single-frequency radiation (for example, spectral lines) when the radiating bodies (atoms, molecules, etc.) have different velocities. Radiation from each individual radiating body has a different Doppler shift, and the collection of radiations at different frequencies broadens the peak of the line in an intensity-vs-frequency plot.
