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. WebThe proposed incoherent integration detection model. In Figure 3, system parameters mainly refer to the platform height and the elevation wave position in the fast time data process when the radar transmits a burst of pulses.
