Frequency dependence of acoustic‐wave scattering from randomly rough surfaces

Using numerical techniques presented in a previous paper [J. C. Novarini and J. W. Caruthers, J. Acoust. Soc. Am. 53, 876–884 (1973)], the statistical character of five acoustic fields in the range 0.75–3.00 kHz scattered from an ensemble of model sea surfaces for a wind speed of 4 m sec⁻¹ is presented. Total intensity, degree of coherence, and phase and amplitude fluctuations are studied in the range of transition from a smooth to a rough surface.
