An Analytical Formulation of the Correlation of GNSS-R Signals
IEEE Transactions on Geoscience and Remote Sensing, 2022 We present an analytical formulation of the correlation coefficient of the electromagnetic fields scattered at near-specular direction by a rough or gently undulating surface and measured at two spatially separated positions occupied by a moving receiver at slightly different times.

Crosstalk Statistics and Impact in Interferometric GNSS-R [PDF]
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016 This paper presents a statistical analysis of the crosstalk phenomenon in interferometric Global Navigation Satellite Systems Reflectometry (iGNSS-R). Crosstalk occurs when the Delay-Doppler Map (DDM) of a tracked satellite overlaps others fromundesired satellites.
