High-frequency surface wave radar based on a sea floating antenna concept

The concept of sea floating antenna array is to replace a conventional coastal receive unit by a sea floating array, constituted of a set of receive buoys. Waves and wind introduce movements of buoys in the array which generate disturbances in the array radiation pattern. In this paper, compensation methods for vertical and horizontal displacements are presented. This paper introduces algorithms for both displacements which are tested following different sea states. Then, these algorithms can be combined in series, providing a simple method to optimise the radiation pattern of the deformed array.
