Abstract:
|
This paper presents the computed electromagnetic (EM) bias predicted for GNSS-R altimetry systems. First, a synthetic time-evolving sea surface is generated satisfying an ocean surface height spectrum. Then, a direct GNSS signal recorded by an up-looking antenna is used as the GNSS signal 'illuminating' the synthetic sea surface, and the scattered waves are simulated using the Geometric Optics (GO) method. Finally, using the fundamental definition of the EM bias, it is estimated and compared to the limited existing analytical methods. |
