Claim Text:
1. A method of RF signal processing comprising: receiving an incoming RF signal at each of a plurality of antenna elements that are arranged in a first pattern; modulating the received RF signals from each of the plurality of antenna elements onto an optical carrier to generate a plurality of modulated signals, each modulated signal having at least one sideband; directing each of the plurality of modulated signals along a corresponding one of a plurality of optical channels, each of the plurality of optical channels having an output, the outputs of the plurality of optical channels arranged in a second pattern corresponding to the first pattern; forming a composite optical signal using light emanating from the outputs of the plurality of optical channels; and extracting, from the composite optical signal, non-spatial information contained in at least one of the received RF signals.
