This study investigates the impact of sea surface roughness, influenced by both wind and wave characteristics, on GNSS-R observations using TRITON data. Traditional speed inversion algorithms often simplify Delay-Doppler Maps (DDM) to represent roughness caused solely wind. However, this research highlights critical role that wave-induced plays in scattering microwave signals. To analyze these effects, employs ResNet18 deep convolutional neural network, which excels at handling complex...
