Organizers/chairs: Roman Maršálek (Brno University of Technology), Pavol Galajda (Technical University of Košice)
Date: Friday April 22nd, 10:15-14:00
Description:
This workshop at the International conference Radioelektronika 2022 is focused on human presence and activity monitoring in the most perspective bands, such as millimeter-wave or ultra-wide-bands, and deals with necessary signal processing approaches, presentation of experimental work outcomes and talks on related hardware design aspects.
The workshop consists of a technical session with papers undergoing standard submission, deadline, review and registration policy as other sessions of the Radioelektronika conference. In addition, the technical paper presentations are complemented with a workshop keynote talk and afternoon presentation and discussion of ongoing project activities at Brno University of Technology and TU Kosice.

Title: Geometric tracking based on angular and Doppler information for crowd motion detection
Speaker bio:
Erich Zöchmann received all his degrees (B.Sc., Dipl.-Ing, Dr.techn) in electrical engineering (telecommunications) from TU Wien, Austria. From 2013 to 2015, he was a Project Assistant at TU Wien where he conducted research on 4G mobile communication systems. From 2015 to 2019, he held a position as university assistant at TU Wien, where he was involved in experimental characterization and modelling and data analysis of 5G millimeter wave propagation. From November 2017 until February 2018, he was a visiting scholar at the University of Texas at Austin, USA. From 2019 until 2021, he held a position as Senior RF and Radar Engineer at PIDSO - Propagation Ideas and Solutions GmbH where he was involved in the design of an AESA SAR radar and also conducted research in radar signal processing. Since 2021 he is a Solutions Architect / E2E Lead System Engineer at Kapsch TrafficCom AG where he is concerned with delivering market-leading ETC and ITS solutions. Further, he is a part-time employee at Brno University of Technology, where he consults on RF crowd monitoring applications. Besides data analysis, his research interests include radar, array signal processing, V2X, ETC and ITS solutions.
Abstract:
When wireless communications engineers talk about channel tracking, they are usually referring to tracking the channel in time and frequency domain. However, objects that create this time and frequency selective pattern are physical objects with a relative geometric position with respect to the receiver. If these objects are some people or even a crowd, their trajectory can be of great interest. We show some useful examples and introduce a not-so-familiar tracking strategy that uses a single scanning antenna and narrowband observations. The derived geometric tracker is based on sonar algorithms known as Doppler-bearing tracking. The effectiveness of the approach is still being demonstrated in a vehicular environment, but the relationship to crowd motion detection is shown
Workshop is supported by the project VJ01030008 Passive crowd monitoring system with privacy by design prepared under IMPAKT 1 program.
