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. Webcompared via their intermediate scattering functions (Fig. 7). The ﬁrst dynamical parameter, b [cf. Eq. (36)], was found to be 0 4 for the protein main chain and 0 27 for the side-chains,
