Detecting Targets above the Earth's Surface Using GNSS-R Delay Doppler Maps: Results from TDS-1 [PDF]

open access: yes, 2019
: Global Navigation Satellite System (GNSS) reflected signals can be used to remotely sense the Earth’s surface, known as GNSS reflectometry (GNSS-R). The GNSS-R technique has been applied to numerous areas, such as the retrieval of wind speed, and the
