Abstract
In this paper, a performance study is conducted for a automotive MIMO RADAR antenna mounted behind a painted bumper. Initially, a 2Tx-4Rx MIMO RADAR antenna is designed and placed behind a simplified curved bumper. The individual Tx/Rx antenna is a seven-element series fed modified binomial array. Next, two layers of paint (primer coat and base coat) materials are applied on the bumper and performance of the antenna-painted bumper integrated system is studied using bi-directional loss and antenna array ambiguity function models. The proposed study provides a quantitative analysis into the MIMO RADAR performance matrics like bi-directiola loss, field-of-view and ambiguity in the direction-of-arrival estimation, caused by the real-time antenna-bumper interactions.

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
