Abstract

The study of tropospheric scattering channel propagation characteristics is the basis for establishing a reliable scattering communication system. Before studying the scattering channel propagation characteristics, the propagation mechanisms of scattering are introduced, including turbulence incoherent scattering, irregular layer incoherent reflection, and stable layer coherent reflection, as the theoretical support. For the loss characteristics, several more applicable prediction models for convective-layer scattering link transmission loss are introduced. For the fading characteristics, the causes of fast and slow fading are analyzed, and the power delay spectrum and Doppler power spectrum of the scattering channel are studied. It is shown that the power delay spectrum can be obtained from the inverse Fourier transformation of the autocorrelation function in frequency domain of the received signal, and the Doppler power spectrum can be obtained from the Fourier transformation of the autocorrelation function in time domain of the received signal. The propagation characteristics of the scattering channel and its significance are initially explored theoretical levelly.
