The Extraction Of Sea Surface Wind And Sea State Parameters Transfer, Inversion Characterize The System

HF radar can measure the sea surface parameters. On oceanography, HF radar can be used in researching the property of ocean wave, supervising the sea status timely, getting offshore wind field picture as well. Combine with the project "HF Ground Wave Radar Supervise Sea Status" of state 863 project, retrieving wind direction from HF radar Doppler spectrum and the showing of wind field, current field, wave field are researched in this paper. The problem of how to represent the sea surface parameters by computer is concerned, too.This paper introduces several methods retrieving wind direction from HF radar echo Doppler Spectrum and analyses the feature of those methods. To the problem of getting wind direction from one wave-bind of one radar, this paper brings forward a method of retrieving wind direction from HF radar echo Doppler spectrum based on Genetic Arithmetic (GA), which is a new method to retrieve wind direction. It's also a useful exploration on the application of retrieving the sea parameters using Genetic Arithmetic.To the problem of transmitting the sea parameters, this paper brings forward a Multi-tier Distributed machinery which can transmit and retrieve the sea parameters timely. Designs and implements an Exe-based three-tired Radar Sea Parameters Show system which can resolve the problem of transmitting and retrieving the sea parameters. In the end of this paper, this system is used to process the retrieve and token of wind field, current field, wave field information on ZhouShan trial data.
