Worst-case interference levels from mainlobe-to-mainlobe antenna coupling of systems operating in the radiolocation service into active sensor receivers operating in the Earth exploration-satellite service (active) in the 35.5-36.0 GHz band

This Report presents the worst-case interference levels from antenna mainlobe-to-mainlobe coupling of radiolocation service (RLS) systems into the Earth exploration-satellite service (EESS) (active) receivers in the 35.5-36.0 GHz band using both one-pass simulation and dynamic analyses. The characteristics of two typical spaceborne active sensors operating in the EESS (active) and of two typical RLS systems, are presented. The potential worst-case interference from mainlobe coupling into the EESS (active) receiver from the RLS systems is analysed.
