Paper Abstract

Physical scale modeling of the electromagnetic backscatter behavior of static sea states using dielectric models and indoor compact radar ranges has the potential to offer a unique and advantageous method to probe ocean scattering phenomenology not feasible using conventional radar measurements on dynamic sea surfaces. As an initial step towards developing such modeling techniques, the millimeter-wave backscatter of a static, simplified rough surface made from a material that electromagnetically models the X-band dielectric properties of seawater has been measured. Computational electromagnetic modeling of the surface was performed using Xpatch and is compared with compact range measurements. By starting with simplified sea-state surfaces, the aim is to develop a reliable scale modeling approach capable of studying the backscattering behavior of realistic ocean surfaces.
