Abstract:
An RF transmit signal is modulated onto an optical carrier to form a transmit modulated optical carrier (TMOC). The TMOC is split into N transmit modulated optical subcarriers (TMOS). Each TMOS is respectively processed in one of N transmit optical channels (TOCs). In each TOC, RF antenna beam steering operations are performed by optical tuning the TMOS to selectively control a phase difference between the optical carrier and the optical sideband. A different selected phase difference can be applied in each TOC. The TMOS from each of the N TOCs is then processed to obtain N RF signals for driving an antenna array. In the receive direction, M received RF signals from M antenna elements are modulated respectively onto M optical subcarriers to form M receive modulated optical subcarriers (RMOS). RF antenna beam steering operations are performed by optical tuning the RMOS.

Claim (Index 21):
A method for controlling a phased array antenna system, comprising:\n modulating M received RF signals from M antenna elements respectively onto M optical subcarriers to form M receive modulated optical subcarriers (RMOS), each comprised of a receive optical subcarrier signal and at least one receive optical sideband signal, where M is an integer value greater than 1; processing one of the RMOS respectively in each of M receive optical channels (ROCs); and in each ROC, performing RF antenna beam steering operations by optical tuning the RMOS to selectively control a phase difference as between the receive optical subcarrier signal and the receive optical sideband signal.
