The performance of modern ground-based radar with regard to low altitude coverage are seriously affected by environmental factors such as earth curvature or orographical obstacles. The coming of spatial-era with the first artificial satellites allowed to develope new satellite-based radar systems, able to overcome the former limitations. The present work deals with new concepts and tools to design both primary (PSR: primary surveillance-radar) and secondary (SSR: secondary surveillance-radar) space-borne radars. It is possible to design a near-optimum system configuration (minimum complexity and cost with the required performance) both for primary and secondary space-based radars; the random array architecture seems to be able to meet all system requirements; some features of it have been defined and evaluated.
