An Instrument Error Correlation Model for Global Navigation Satellite System Reflectometry

Remote Sensing
All sensing systems have some inherent error. Often, these errors are systematic, and observations taken within a similar region of space and time can have correlated error structure.

Considerations for Coherent Integration in Spaceborne GNSS-Reflectometry

IEEE Geoscience and Remote Sensing Letters
The fundamental observable in Global Navigation Satellite System Reflectometry (GNSS-R) is the so-called DelayDoppler Map (DDM), which is derived from the cross-correlation of the reflected signal with either the direct signal or a locally generated replica of the transmitted signal as implemented in our algorithm.
