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. WebApr 9, 2024 · The final, optimal, distribution was given by the most frequent 13 b-values identified over the 100 repetitions, considering as frequency the sum of the relative frequencies for all SNR levels. The optimal sets were characterized by 5 b -values in the range [0, 190] s/mm 2 and 5 b -values in the range [300, 1400] s/mm 2 .
