Abstract
In this paper, a joint 4D radar and communication (RadCom) front-end is proposed, developed, and experimentally demonstrated for next-generation automotive sensing and connectivity systems capable of simultaneously sensing azimuth, elevation, range, and velocity. The system leverages the reconfigurable and dynamic properties of Virtual Transceiver Matrix (VTM) to achieve advanced sensing capabilities. Additionally, it integrates real-time inter-vehicle communication to enhance situational awareness. The 4D sensor cells are realized using an interferometric technology, marking the first application of interferometry in 4D radar sensing. A prototype operating in the 24 GHz band is developed to validate the proposed concept. Experimental results from system-level measurements are set to demonstrate the system's potential for automotive applications, showcasing its effectiveness and versatility.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
