Incoherent vs coherent scattering

Webof incoherent scatter radars is conveniently measured in megawatt-acres. There are just a dozen ISRs operating around the world. In addition to incoherent scatter, “coherent scatter” can a lso be detected by radars and used to probe the ionosphere at many altitudes. The meaning of this term is somewhat ambiguous but gen- Webwith coherent scattering (see above), whereas if the electron is ejected from the atoms, the scattering is (incoherent) Compton scattering.
