    "abstract": "In this paper we focus on the microwave bistatic scattering process, with the\naim of deriving an expression for the interferometric complex field\nauto-correlation function from a static platform. We start from the Fresnel\nintegral and derive the auto-correlation function in the Fraunhofer and\nModified Fraunhofer regime. The autocorrelation function at short times can be\nexpressed as a Gaussian with a direction dependent time scale. The directional\nmodulation is a function of the angle between the scattering direction and the\nwave direction. The obtained relation can be used for directional sea state\nestimation using one or more GNSS-R coastal receivers.",
