Measurement-based Validation of Ray-tracing Model at sub-THz for ISAC Applications of Blockage in Industrial Scenario

The present paper compares double-directional ultra-wideband measurements at 187.5 GHz with ray tracing (RT) simulations using the open-source tool Sionna. The objective is to validate a model obtained from precise light detection and ranging (LiDAR) scans. The measurements emulated a sensing system in a situation of blockage by a forklift truck in an industrial scenario. The results show, despite expected differences, a good agreement between the measurements and simulations, enabling this model for further investigations on machine learning (ML)-based integrated sensing and communication (ISAC) algorithms.
