Webthe incoherent radiation it generates does not give rise to interference effects and therefore is negligible at Bragg peaks. However, as the scattering volume is reduced, the difference … 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.

"WebThe average scattering length is. b = abc + (1 − a)bd, and the average incoherent cross section can be calculated by an average over the isotope abundances: σinc 4π = (δb)2 = a(bc − b )2 + (1 − a)(bd − b )2 = a(1 − a)(bc − bd)2. This means that we see an incoherent scattering due to the isotope mixture, strongest at 50%-50% ... " - Incoherent vs coherent scattering
