Abstract
Mathematical modelling and propagation data measurements of a continuous wave (CW) signal over a water path have been carried out to study the multipath phenomena and their effects on the performance of tracking radars operating against low flying objects and, eventually, to seek for solution to improve their presently unsatisfactory performance. The mathematical model, which is originated from sea swell modelling, is developed to study the mechanism of the forward scattering from rough sea surfaces and/or sea swells. It is based on the theory of representing a sea surface by a continuum of aperture antennas. Simulations were carried out and results were satisfactory. Two multipath measurements were conducted in the past two years. One was over Lake Huron in November, 1987 and the other oved Lake Ontario in November, 1988.
