Abstract:

This paper summaries a series of measurements which were aimed at studying the phenomenon of multipath resulting from line of sight, two way, microwave propagation over the sea surface. It has been observed tha the expected lobing structure, due to the interference of the direct and reflected signals is destroyed when the sea surface becomes sufficiently rough, suggesting teh coherent part of the forward scattered sea reflection to be zero. Further, it has been observed that although the pulse by pulse fluctuations show deep fading characteristics they may be modelled by the Rice-squared distribution. However, it has been found that care must be taken in choosing the duration of the measurement when evaluating the statistical properties of the data. Author
