WebIncoherent scatter radar theory is the most well recognized applied technique for studying the Earth's ionosphere, which was first proposed by Professor William E. Gordon in 1958. In this sense, a radar beam scattering off electrons in the ionospheric plasma produces an incoherent backscatter. Weberally means scattering that is stronger than incoherent scatter but weaker than total reﬂection. The detection of coherent radar scatter generally implies the existence nonthermal irregularities in the plasma, indicative of free energy, waves, and instabilities.
