We focuse on simulation principles and techniques of GNSS-R in sea surface wind field (SSWF) retrieval based on airborne remote sensing, and analyze the relationship among ocean wave spectrum, sea surface slope, wind speed and direction. We not only carry out a numerical simulation on the condition of various wind speeds and directions, receiver altitudes, and flight speeds, but also have completed a corresponding simulation software. The simulation results indicate that all the parameters above can affect the peak value and the trailing slope of the relative power waveform of the reflected signals from sea surface. Simulation study of this paper establishes a theoretical basis for the SSWF retrieval using GNSS-R.
