Abstract : Reflection coefficient and time studies are reported for an over-water path in the Gulf of Mexico. Measurements were made at wavelengths of 9.0, 5.3, 3.2, and 0.86 cm, and for grazing angles up to 2.5 deg. Simultaneous ocean wave recordings were made. The reflection characteristics were those associated with a plane surface for the longer wavelengths but showed some deviation from those predicted at the shorter wavelengths. Dual receiving antenna studies suggest the difficulty in trying to null out a wave reflected from a rough surface. (Author)
