Abstract
A major obstacle in ultra-wideband radar based approaches for object detection concealed on human body is the difficulty in collecting high quality radar signal data. Generative adversarial networks (GAN) have shown promise in synthesizing data for image and audio processing. This paper proposes the design of a GAN for application in radar signal generation. Data collected using the Finite-Difference Time-Domain (FDTD) method on three concealed object classes (no object, large object, and small object) are used as training data. A GAN is trained to generate radar signal samples for each class. The proposed GAN is capable of synthesizing the radar signal data which is indistinguishable from the training data by qualitative analysis performed by human observers.

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
