Research and simulation of radio reflection characteristics of sea surface in the S-band

The electromagnetic wave will be reflected when encountering high and low waves during the propagation of the sea. The signal received by the wireless communication system receiver is composed of a direct signal and many reflected waves with different amplitude fading and phase. In this paper, for the S-band, the characterization parameters of sea surface electromagnetic characteristics and sea surface radio wave reflection characteristics - seawater dielectric constant and reflection coefficient are respectively studied, and their calculation methods are discussed. According to the change law, the main factors affecting its change and the aspects that should be paid attention to in the actual calculation are obtained. The research in this paper can provide a valuable reference for the study of the reflection characteristics of sea surface radio waves.
