Multi-Mission GNSS-R Raw IF Data: Exploration and Application

Earth reflected Global Navigation Satellite System (GNSS) missions provide as a main product the delay-Doppler map (DDM) of the power of the reflected GNSS signals. Some of these missions have collected a large amount of raw intermediate frequency (IF) data. Due to the unprocessed nature of these raw IF data provides an unique opportunity to explore the potential of GNSS Reflectometry (GNSS-R) technique for advanced geophysical applications such as inland water detection and surface altimetry.
