Abstract: DLOS and reflected signal components of an RF carrier signal are received. The reflected component is reflected from a point on the surface of the earth. The DLOS and reflected components are converted to digital DLOS IF and reflected IF signals, respectively. Modeled parameters are generated using the digital DLOS IF signal and locations of one or more antennas, the transmitter, and the point. A reference signal is generated based on the modeled parameters. The reference signal is correlated with the digital reflected IF signal to produce in-phase and quadrature-phase correlation results. A C/N0 and an estimated phase (EP) are calculated for the digital reflected IF signal from the correlation results. A KF is applied to the EP to produce an estimated filter phase (EFP). The KF is adapted to filter the EP using the estimated C/N0 to reduce cycle slips and noise in the EFP.
