Talk 2: Software Defined Radio (SDR) Passive Radar Implementations

Speaker: Jean-Michel Friedt

Affiliation: University of Franche-Comté

Academic title: Associate  Professor

Abstract:

Software Defined Radio (SDR) provides the stability, flexibility and reconfigurability of software applied to discrete-time signal processing of radiofrequency signals. These features make it ideally suited to passive radar signal processing in which non-cooperative signals are used to detect targets. In this presentation, we will step-by-step demonstrate the implementation of various SDR-based passive radar schemes using digital video broadcast television signals, selected for their bandwidth and strong emitted power, two features needed for radar applications. Based on the open-source GNU Radio framework, we will also illustrate how to reprogram the data collection hardware for frequency stacking, synchronize data collection with antenna positioning for target angle retrieval, or use spaceborne moving radiofrequency sources for 2D target imaging. Since passive radar applications might be limited by the availability of signals, the presentation concludes with covert radar applications where widely available consumer grade radiofrequency sources are used to illuminate the targets.

Biography:

Jean-Michel Friedt was trained as a physicist and obtained his PhD in 2000 on biosensor measurements using acoustic and optical transducers combined with scanning probe microscopy techniques. After spending 10 years in a company developing short range radar systems for probing wireless, passive sensors using acoustic wave transduction on piezoelectric substrates, he joined Franche-Comte University (France) in 2014 as associate professor, with his research activity hosted by the Time and Frequency department of FEMTO-ST (Besancon, France). His research interests currently focus on opensource, openhardware software defined radio (SDR) frameworks for time and frequency transfer, including (passive and covert) radar applications.
