A general formulation is given of the power spectrum of the fluctuations in the signal recieved by way of reflection from a rough sea surface, in terms of an arbitrary wavenumber-frequency spectrum of the surface waves and an arbitrary source directivity function. The formulation is specifically applied to a backscatter situation, and the extreme cases of acoustically slightly rough and very rough sea furfaces are examined in detail. The relevance of the results to experiments, to sonars and to radar-backscatter sensing of the sea surface are discussed. Author
