Topographic mapping from interferometric
WebAbstract: This paper presents results of a study of the feasibility of Ka band slot arrays for an interferometric radar for the purpose of topographic mapping of the outer planets such as Jupiter and its moons. A small array is designed, built and tested. WebInterferometric SAR observations are a basis for the generation of high resolution topographic maps of a region through the interpretation of interference fringes. The …
