WebDuring their passage of the ionosphere, radiowaves get disturbed and phase and amplitude fluctuations are measured at the ground. These amplitude and phase fluctuations of the recorded signal are statistically characterised by two major parameters, amplitude and phase scintillation indices, denoted respectively by S4 and σ Φ. Web7 nov. 2024 · Marconi’s experiment demonstrated that radio signals did not travel in a straight line, but bounced off an atmospheric layer—the ionosphere. The ionosphere is broken into distinct layers, called the D, E, F1, and F2 layers. Like all other parts of the atmosphere, these layers vary with season and latitude.
