Optically smart X-band antenna array

Summary form only given. We demonstrate an optical processor that extracts the principal components of the spatiotemporal signals incident on an X-band antenna array. The entire system, including the microwave receiver and optical processor is packaged in a 33 cm x 45 cm by 15 cm briefcase and consumes less than 50 W of continuous power. The adaptive receiver system can be used, for example, to mitigate multipath interference effects, and can separate one received signal from another even though their power spectra may entirely overlap. The receiving antenna is a 10 GHz antenna lens array.
