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- WebSuperDARN chooses to use coherent scatter radars due to the benefits to the science and experiment itself. Coherent radars generally have a much lower time and range resolution (~mins, ~10s km) than incoherent (~secs, ~100s m), but can operate at varied frequencies, at much lower power and consider a much large field of view.
