Radar sea clutter modeling, with associated data gathering and analysis, is reported with specific emphasis on clutter returns with a probability of occurrence of a minimum of 1 in 1,000,000 referenced to the mean. Data was gathered and reduced as a function of sea state, wind direction, grazing angle and polarization off the East and West Coasts with a basic radar resolution of 100 by 100 feet at X-band. Analyses reported characterize sea clutter in terms of mean clutter backscatter coefficient sigma sub 0, probability density, statistical variability, temporal and spatial power spectral density and autocorrelation function, and conditional probability. Models of sea clutter are formulated and validated by simulation with several levels of refinement for use primarily in specification, design and evaluation of missile systems. The material is presented in a form to be useful in other applications as well. Although this report is presented in four volumes, attention should be directed primarily to Volume 1 which, on a stand-alone basis, contains an overview and presents summarized results and the full clutter models.
