Abstract

Monte Carlo simulations were performed to predict the statistical errors in satellite based wind speed measurements using bistatic GPS signals. A scattering model based upon geometric optics and empirical ocean surface slope variances was used to simulate the mean post-correlation waveform. Synthetic Rayleigh scattered and thermal noise signals were generated. Batches of between 50 and 1000 independent samples were used in these simulations. The surface resolution was set to a radius of approximately 50 km through selection of range and Doppler bins
