Millimeter-wave imaging system using a 60 GHz dual-polarized AFTSA-SC probe
Bibliographic record
Abstract
An experimental evolution of the imaging detection system's 57–64 GHz ISM-band probe for security checkpoint applications is presented. The Dual-polarized antipodal Fermi tapered slot antenna with sin-corrugation (DP-AFTSA-SC) is a low profile microstrip probe that is lightweight, high gain and broadband, and achieves a good standard MMW image. The DP-AFTSA-SC antenna is employed as a sensor. Its performance is compared with the standard gain horn (SGH) for use in imaging/detection systems with a short pulse based on time domain reflectometry (TDR) generated by a PNA network analyzer. The targets are placed on material emulating the human body. The image is reconstructed using a 2D linear scanning platform with a cross range resolution achieving a 100 × 100 pixel image. Resolutions for reconstructed images scanned with the proposed low profile DP-AFTSA-SC probe are of similar quality to those generated using the SGH antenna.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
