US Patent No: 4620193

Optical phase array radar

---

Abstract

---

In an optically controlled phased array radar control information in the form of microwave frequency modulation of an optical carrier is transmitted by optical waveguide from a central processor to each of the antenna elements. Phase shifts introduced by each of the individual waveguides are then monitored to provide a compensation signal used either to regulate the phase shift or to offset the phase of the modulation applied to the waveguide at the central processor end.
