Among the different ocean physical parameters applied in the hydrographic studies, sufficient work
has not been noticed in the existing research. So it is planned to evaluate the wave height from the satellite
sensors (OceanSAT 1, 2 data) without the influence of tide. The model was developed with the comparison of
the actual data of maximum height of water level which we have collected for 24 h in beach. The same
correlated with the derived data from the earlier satellite imagery. To get the result of the significant wave
height, beach profile was alone taking into account the height of the ocean swell, the wave height was deduced
from the tide chart. For defining the relationship between the wave height and the tides a large amount of good
quality of data for a significant period is required. Radar scatterometers are also able to provide sea surface
wind speed and the direction of accuracy. Aim of this study is to give the relationship between the height, tides
and speed of the wind, such relationship can be useful in preparing a wave table, which will be of immense
value for mariners. Therefore, the relationship between significant wave height and the radar backscattering
cross section has been evaluated with back propagation neural network algorithm.
