     abstract = "{The Earth's time-variable gravity field holds significant research and
        application value. However, satellite gravimetry missions such
        as GRACE and GRACE-FO face limitations in spatial resolution
        when detecting monthly gravity fields, while traditional radar
        altimeters lack the observational efficiency needed for monthly
        gravity anomaly inversion. These limitations hinder further
        exploration and application of the Earth's time-variable gravity
        field. Leveraging its advantages, such as rapid global coverage,
        high revisit frequency, and low cost for constellation
        formation, spaceborne GNSS-R technology holds the potential to
        address the observational efficiency gaps of traditional radar
        altimeters. This study presents the first assessment of the
        capability of spaceborne GNSS-R interferometric altimetry for
        high spatial resolution monthly marine gravity anomaly inversion
        through simulations. The results indicate that under the PARIS
        Operational scenario of a single GNSS-R satellite (a spaceborne
        GNSS-R interferometric altimetry scenario proposed by Martin-
        Neira), a 30' grid resolution marine gravity anomaly can be
        inverted with an accuracy of 4.93 mGal using one month of
        simulated data. For a dual-satellite constellation, the grid
        resolution improves to 20', achieving an accuracy of 4.82 mGal.
        These findings underscore the promise of spaceborne GNSS-R
        interferometric altimetry technology for high spatial resolution
        monthly marine gravity anomaly inversion.}",
