PROJECT WAVE AN EXPERIMENTAL AND THEORETICAL STUDY OF SCATTERING FROM WATER WAVES.
Abstract
A formulation of the physical optics theory particularly applicable to microwave scattering from water surfaces was developed. The special case of backscattering from simple gravity waves was investigated, and expressions obtained for the scattering amplitudes from both smooth waves and rough waves. A simple model based on the assumptions that individual area elements of the water surface scatter independently with a Lambert's law distribution, and that the power scattered from an element is Doppler shifted in accord with the fluid velocity at the element was considered in detail. Applications of this model to trochoidal waves were made using expressions for particle trajectories and velocities derived from the theory of hydrodynamics. Results of experiments utilizing a wave tank and an X-band, CW Doppler radar are described and compared with predictions of the theory. (Author)
