Frequency-scanned waveguide-fed slot array for millimetre-wave radar applications
Bibliographic record
Abstract
Millimetre-wave designs have become increasingly common in radar applications due to advantages when compared with traditional microwave designs. The increased operating frequencies offer greater bandwidths and allow for reduced antenna sizes. In radar systems, large bandwidths are used to achieve high range resolutions. At millimetre-wave frequencies, there is sufficient bandwidth for additional uses, most notably, beam steering using a frequency-scanning antenna. Due to their simplicity, these antennas are particularly attractive for commercial radar applications. In this work, a millimetre-wave frequency-scanned slot array was designed based on a serpentine waveguide for a 1.8 GHz bandwidth centred at 34.3 GHz. The antenna was fabricated, and measurements indicated a range resolution better than 1.25 metres over an angular scanning range of 20 degrees. The antenna was incorporated in a simplified radar system, which successfully demonstrated the ability to detect and locate multiple targets simultaneously.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
