Research on UAV Multipath Signal Propagation Characteristics on Sea Surface Based on Wen's Spectrum Wave
Aiming at the maritime communication scenario of UAV,the multipath signal propaga-tion characteristics on the sea surface are mainly studied and analyzed.The wave model modeling based on Wen's spectrum is completed.The influence of waves on multipath signal propagation is ana-lyzed,and the UAV multipath signal propagation model of sea surface suitable for different sea condi-tions is established.The number of effective reflection points of multipath signal and the attenuation amplitude of multipath signal under different sea conditions are obtained by simulation,and the BER curve of UAV communication link is given.The analysis results show that the harsh degree of sea con-dition determines the multipath signal propagation status on the sea surface,which in turn interferes with the effectiveness of the UAV communication system.The study has great significance for the de-sign of the maritime UAV communication system.
