基于卫星遥感资料的近海海上通信环境研究
Research on the Offshore Marine Communication Environment Based on Satellite Remote Sensing Data
摘要
Abstract
Air-sea interface fluxes significantly impact the reliability and efficiency of maritime communication.Compared to sparse in-situ ocean observations,satellite remote sensing data offers broader coverage and extended temporal span.This study utilizes COARE V3.5 algorithm to calculate momentum flux,sensible heat flux,and latent heat flux at the air-sea interface,based on satellite synthetic aperture radar(SAR)wind speed data,reanalysis data,and buoy measurements,combined with neural network methods.Findings indicate that SAR wind speed data corrected via neural networks show improved consistency with buoy-measured wind speeds in flux calculations.Specifically,the bias in friction velocity decreased from-0.03 m/s to 0.01 m/s,wind stress bias from-0.03 N/m² to 0.00 N/m²,drag coefficient bias from-0.29 to-0.21,latent heat flux bias from-8.32 W/m² to 5.41 W/m²,and sensible heat flux bias from 0.67 W/m² to 0.06 W/m².Results suggest that the neural network-corrected SAR wind speed data can provide more reliable environmental data for maritime communication.关键词
