Abstract EN
The significant wave height (SWH) retrieved from collocated HH and VV polarized X-band marine radars under different sea states is studied.
The SWH are retrieved from different principal components of X-band marine radar image sequence.
As compared with the SWH measured by a buoy, the root-mean-square errors of the SWH are 0.32–0.45 m for VV polarization, and they are 0.37–0.60 m for HH polarization.
At the wind speeds of 0–5 m/s, the SWH can be derived from VV polarized radar images, while the backscatter of HH polarized radar is too weak to contain wave signals at very low wind speeds (~0–3 m/s).
At the wind speeds of 5–18 m/s, the SWH retrieved from VV polarization coincide well with the SWH measured by the buoy, while the SWH retrieved from HH polarization correspond with the changes of the wind speed.
At the wind speeds of 18–26 m/s, the influence of wave breaking on HH polarization is more important than that on VV polarization.
This indicates that the imaging mechanisms of HH polarized X-band marine radar are different from those of VV polarized X-band marine radar.
