Abstract

fetched live from OpenAlex

This work proposes and studies a super fusion procedure to stitch simultaneous, non-equal, and non-contiguous frequency bands together to increase the range and velocity resolution in FMCW radars. A comprehensive theoretical analysis is set to predict the resolution of such a super fusion procedure with several bands. A complete experimental verification has been conducted to verify the linear summation of the contribution of each band. Our procedure have successfully shown that three bands (B<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</inf>= 300 MHz,B<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> = 200 MHz,B<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> = 100 MHz) with a measured resolution of 0.41m, 0.62m and 1.24m, respectively, can be fused together to obtain an equivalent 600 MHz band with a resolution of 0.32m. This super fusion procedure is believed to have great potential in reducing the actual RF congestion by splitting necessary radar bands into thinner sub-bands.

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.
