Accurate knowledge of clutter echo characteristics is important in the design of optimum processors for the detection of targets by an airborne radar against land and sea clutter. This paper presents the results of the first clutter measurements carried out over Indian terrain (farmland and sea) from an airborne platform using a `S' band radar. The mean backscatter coefficient is first computed for land and sea clutter and the fluctuation statistics of the clutter echo around the mean are then described by Weibull and lognormal probability distribution functions. The values of the distribution function parameters have been estimated using two different techniques. The development of a theoretical model based on the full wave solution technique for computing the scattering from sea surfaces modelled as a random rough surface has also been presented in the paper. The theoretical prediction have been compared with the experiments.
