Photonic Correlator Processes Radio-Frequency Signals, Outperforms Digital Methods
WASHINGTON, D.C., March 31, 2022 — A team at the University of Grenoble Alpes-CNRS has created a radio-frequency (RF) correlator, based on a photonic platform, that is suitable for analog wideband RF signal processing and that enables the real-time calculation of RF signal correlation across a broadband. Correlation of RF signals is a requirement for many applications, including imaging, information processing, and sensing and detection. The analog, photonic-based lag correlator outperforms conventional analog and digital
