Abstract
In this paper, we develop, MARS, a Millimeter wAve (mmWave) Rotating Synthetic aperture radar (ROSAR) platform that can scan a 360° view of the environment. The platform consists of a radar attached to the edge of a rotating plate. As the plate spins, the radar transmits signals that reflect off the targets in the surroundings. By applying the Back-Projection Algorithm (BPA) on the collected data, we can reconstruct high-resolution images of the target area. However, BPA is computationally intensive. To speed up the imaging process, we propose two methods: range-FFT and GPU acceleration. Experiments show that MARS can successfully generate images of the indoor environments, and that GPU acceleration can reduce the time cost up to 98% compared to the conventional BPA.

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
