Abstract:
|
The effectiveness of incoherent averaging depends on
the level of correlation between consecutive waveforms,
which can vary with the geometry and with the sea state
conditions. In addition it is also dependent on the lag
position, since the level of correlation is not the same for all
the lags. An initial estimation of the lag correlation can be
done by means the ratio (R) between the actual number of
incoherent averages and the effective number of incoherent
averages.
This work is structured in two parts: In the first part the
concept of using of the ratio R as a new observable to
estimate the significant wave height is detailed. In the
second part, data from the TIGRIS experiment is used in
order to relate the R with the significant wave height,
comparing its performance with the performance obtained
with the coherence time. |
