Abstract
Frequency modulated continuous wave (FMCW) radar technique has been widely used in tracking system, e.g., WiTrack System. In this paper, based on fourth order statistic, i.e., Kurtosis (KD), we propose a non-coherent CFAR detection method for FMCW indoor positioning. We develop mathematical model, investigate impacts of parameters and conduct performance evaluations. Our results show the proposed Kurtosis based detection outperforms the conventional FMCW detection technique under additive white Gaussian noise (AWGN), line-of-sight (LOS) and non-line-of-sight channel conditions. The detection probability with the proposed method can be twice better than the conventional method.

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
