Abstract
Analog optical signal processing of complex radio-frequency signals for range-Doppler radar information is theoretically described and experimentally demonstrated using crystalline optical memory materials and off-the-shelf photonic components. A model of the range-Doppler processing capability of the memory material for the case of single-target detection is presented. Radarlike signals were emulated and processed by the memory material; they consisted of broadband , spread-spectrum, pseudorandom noise sequences of in length, which were binary phase-shift keyed on a carrier and repeated at over . Delay (range) resolution of and Doppler resolution of over were demonstrated.
