Publication number: 20230109253Abstract: A method of RF signal processing comprises receiving an incoming RF signal at each of a plurality of antenna elements that are arranged in a first pattern. The received RF signals from each of the plurality of antenna elements are modulated onto an optical carrier to generate a plurality of modulated signals that each have at least one sideband. The modulated signals are directed along a corresponding plurality of optical channels with outputs arranged in a second pattern corresponding to the first pattern. A composite optical signal is formed using light emanating from the outputs of the plurality of optical channels. Non-spatial information contained in at least one of the received RF signals is extracted from the composite signal.Type: ApplicationFiled: November 29, 2022Publication date: April 6, 2023Inventors: Chris Schuetz, Janusz Murakowski, Garrett Schneider, Shouyuan Shi, Dennis Prather

Patent number: 11069974Abstract: An optically-fed tightly-coupled array (TCA) antenna comprises a plurality of photodiodes and antennas. Each photodiode may receive an optical signal from an optical fiber and convert the optical signal into an RF driving signal to drive a corresponding antenna to which it is connected. Each photodiode may be connected to the antenna. In some examples, the TCA is capable of ultra-wideband operation ranging from 2-12 GHz and wide beam-steering capability up to 40° from the broadside. Inductance peaking and resistance matching may be employed.Type: GrantFiled: November 18, 2019Date of Patent: July 20, 2021Assignee: Phase Sensitive Innovations, Inc.Inventors: Shouyuan Shi, Jian Bai, Chris Schuetz, Garrett Schneider, Dennis Prather

Patent number: 10911142Abstract: An optical imaging system and method that reconstructs RF sources in k-space by utilizing interference amongst modulated optical beams. The system and method involves recording with photodetectors the interference pattern produced by RF-modulated optical beams conveyed by optical fibers having unequal lengths. The photodetectors record the interference, and computational analysis using known tomography reconstruction methods is performed to reconstruct the RF sources in k-space.Type: GrantFiled: February 25, 2019Date of Patent: February 2, 2021Assignee: Phase Sensitive Innovations, Inc.Inventors: Janusz Murakowski, Chris Schuetz, Garrett Schneider, Shouyuan Shi
