Photonics for Jamming Tolerant Wideband RF Communications

A microwave photonic architecture for jamming tolerant RF transmission of wideband 10-100 Mbps data is analyzed. Switched optical delays implement spread-spectrum encoding and sliding-window decoding of the RF-carrier phase. Any strong jammers are selectively attenuated by a frequency agnostic photonic limiter and further attenuated by the decoder and bandpass filter.
