Abstract

Method and apparatus for a receive electronically steered array aperture including a plurality of radiators each having a single complex phase/amplitude control at a radiating phase center of the radiators to simultaneously receive up to four circularly polarized plane waves, each of the plane waves being arbitrarily of left hand circular polarization or right hand circular polarization, from spatially diverse sources.

Claims

1. A receive electronically steered array aperture, comprising:

a plurality of radiators each having a single complex phase/amplitude control at a radiating phase center of the radiators to simultaneously receive up to four circularly polarized plane waves, each of the plane waves being arbitrarily of left hand circular polarization or right hand circular polarization, from spatially diverse sources.
