Mining noise data for monitoring Arctic permafrost by using GNSS interferometric reflectometry

, 2021
Ground surface elevation changes are closely linked to the dynamics of the active layer and near-surface permafrost. GNSS interferometric reflectometry (GNSS-IR), a technique utilizing reflected signals regarded as noise in the GNSS applications, such as

DME/TACAN Impact Analysis on GNSS Reflectometry [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016
Global navigation satellite system reflectometry (GNSS-R) is becoming a widely accepted technique for remote sensing. The interferometric technique (iGNSS-R) correlates the direct signal received from a satellite and the same signal reflected on the Earth's surface, whereas the conventional technique (cGNSS-R) correlates the reflected signal with a ...
