Volatility Modeling for Ocean Significant Wave Height Estimation

In a previous paper by the same authors in the current conference series [1], an interesting relation was derived which showed that the significant wave height H s is linearly proportional to the standard deviation of the received time series from a monostatic HF radar. In the current paper we use this relation along with methods from the field of volatility modeling, which is often used in financial mathematics, to provide accurate estimates of significant wave height. We demonstrate on field data from Argentia, Newfoundland, Canada that the use of such methods gives slightly more accurate H s estimates than using a simple windowed variance calculation.
