摘要

Radar backscatter off the sea at low incidence angles was measured. A low frequency spectral analysis method is used to show that an appreciable periodic content exists in the sea return. This component in the scintillation spectra is 0.14 Hz and is related to the sea wave period. Wind-wave interaction effects are observed for up, down and crosswind directions. The clutter patch size and the incidence angle are used as a parameter. An optimum spectral response exists for upwind observations at an incidence angle of 1 deg and pulselength 0.08 microsec. The radar cross section per unit area measured is compared with an experimental sea clutter model. For wind directions resulting in an adequate fetch over open sea, reasonable agreement is found. No significant conclusions can be drawn with respect to megaripple observations.
