Abstract
An antenna system includes N movable antenna elements configured to generate concurrently M receiving beams pointing respectively at M satellites radiating in a common frequency band, N and M being integers and N≥M≥2. A beam forming system is coupled to the N movable antenna elements and configured to shape the M receiving beams using weights inputted from a beam controller. The beam controller optimizes the M receiving beams by computing spatial displacements to spatially reposition the N movable antenna elements relative to each other, using an iterative optimization processing to satisfy a plurality of constraints concurrently. A position driver system spatially re-positions the N movable antenna elements in accordance to the spatial displacements inputted from the beam controller.
