Detection of Bohai Bay Sea Ice Using GPS-Reflected Signals

Abstract: For preventing the effects of sea ice disaster, traditional methods for detecting sea ice have some disadvantages, such as inadequate robustness against weather and high cost of real-time detection. This paper evaluates the usage of Global Positioning System (GPS)-reflected signals for accurate real-time Earth observations to study the changes in the sea surface state through remote sensing (RS). GPS L1 signals received after reflection from Bohai Bay were analyzed for their sea-ice content. The results are in… Show more

“…In addition, the distance between successive CYGNSS measurements is about 6 km. Examples of studies that use different platforms can be found in, e.g., [46][47][48][49][50] for spaceborne, [26,[51][52][53] for airborne, and [32,[54][55][56][57] for ground-based applications, respectively.…”

The successful launch of the TechDemoSat-1 (TDS-1) in 2014 created opportunities of spaceborne GNSS-R for sea ice study as a large number of datasets collected over the Arctic and Antarctic region are available online (www.merrbys.co.uk) [25].…”

“…Since then, reflections of GNSS signals from different types of surfaces have been widely studied. Several remote sensing applications presently using GNSS-R technology include ocean altimetry [7][8][9][10], ocean wind [11][12][13], ocean wave sensing [14][15][16], and sea ice detection [17][18][19]. In addition, the possibility of detecting an oil-slicked sea surface using GNSS-R technology simulation has been investigated by Valencia et al [20,21].…”
