| Zusammenfassung |
| Ocean surface, grazing-angle radar backscatter data from two
separate experiments, one of which provided coincident time series of measured surface
winds, were found to exhibit signatures of deterministic chaos. Evidence is presented that
the lowest dimensional underlying dynamical system responsible for the radar backscatter
chaos is that which governs the surface wind turbulence. Block-averaging time was found to
be an important parameter for determining the degree of determinism in the data as
measured by the correlation dimension, and by the performance of an artificial neural
network in retrieving wind and stress from the radar returns, and in radar detection of an
ocean internal wave. The correlation dimensions are lowered and the performance of the
deterministic retrieval and detection algorithms are improved by averaging out the higher
dimensional surface wave variability in the radar returns. |
