Enabling Joint Radar-Communication Operation in Shift Register-Based PMCW Radars

no code implementations24 May 2023 Lucas Giroto de Oliveira, Elizabeth Bekker, Axel Diewald, Benjamin Nuss, Theresa Antes, Yueheng Li, Akanksha Bhutani, Thomas Zwick

Finally, results from proof-of-concept measurements are presented to illustrate the effects of the choice of system and signal parameters and validate the investigated PMCW-based RadCom system and synchronization strategy.

Discrete-Fresnel Domain Channel Estimation in OCDM-based Radar Systems

no code implementations21 Jul 2022 Lucas Giroto de Oliveira, Benjamin Nuss, Mohamad Basim Alabd, Axel Diewald, Yueheng Li, Linda Gehre, Xueyun Long, Theresa Antes, Johannes Galinsky, Thomas Zwick

This article investigates the suitability of the aforementioned discrete-Fresnel domain channel estimation in OCDM-based radar systems as an alternative to the correlation-based processing previously adopted, e. g., in the radar-communication (RadCom) literature, which yields high sidelobe level depending on the symbols modulated onto the orthogonal subchirps.

Quasi-Monostatic Antenna Displacement in Radar Target Simulation

no code implementations7 Feb 2022 Axel Diewald, Benjamin Nuss, Thomas Zwick

Radar target simulators (RTS) have recently drawn much attention in research and commercial development, as they are capable of performing over-the-air validation tests under laboratory conditions by generating virtual radar echoes that are perceived as targets by a radar under test (RuT).

Two-Dimensional Arbitrary Angle of Arrival in Radar Target Simulation

no code implementations7 Feb 2022 Axel Diewald, Benjamin Nuss, Johannes Galinsky, Thomas Zwick

Since an operational failure presents a potential risk to human life, thorough and practical validation testing must be performed, requiring an integrative test solution.
