Abstract

fetched live from OpenAlex

In the context of indoor human localization and tracking using millimeter-wave radar, the multipath effect often introduces false ghost targets, which significantly interfere with the accurate detection of real targets. To address this challenge, we establish a comprehensive multipath propagation model and conduct an in-depth analysis of target characteristics across the range, Doppler, and angle domains. Building on these insights, we propose a novel multipath ghost removal algorithm, termed MGR-RDA, which operates on the three-dimensional radar data cube (Range, Doppler, Angle). Experimental evaluations demonstrate that the proposed method effectively suppresses ghost targets, achieving a recognition accuracy of 98%. Notably, the algorithm performs exceptionally well even in unknown environments without prior information, offering a reliable and practical solution for leveraging millimeter-wave radar in complex indoor scenarios.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not 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.
