机载GNSS-R海面风场信号处理技术研究
Research on airborne GNSS-R signal processing technology of sea surface wind field
摘要
Abstract
The study of correlation power of sea surface scattering signal for the global navigation satellite system (GNSS) has important significance for the inversion of the sea surface wind speed. Under the condition of low signal-to-noise ratio,the traditional method can′t capture the satellite signal successfully and get the correlation power of the sea surface scattering signal. Therefore,a method used to acquire the correlation power of the sea surface scattering signal by extending the coherent integra-tion time is presented and simulated. The simulation result is compared with that of the traditional method. It is found that the method can capture the satellite signal,improve the sensitivity of the receiver,and draw the correlation power waveform of the sea surface scattering signal accurately.关键词
