Programmable and single-shot chirped microwave pulse compression using an optical fiber-based microwave dispersive line
Bibliographic record
Abstract
An approach for programmable single-shot chirped microwave pulse compression is proposed and experimentally demonstrated based on an optical fiber-based microwave dispersive line. The microwave dispersive line is implemented based on a time-spectrum convolution system. This proposed technique has three key features. The first feature is that non-periodic input chirped microwave pulses can be single-shot compressed. The second one is that the compression system is programmable by shaping the spectrum of a broadband multi-wavelength laser or by tuning the first-order dispersion of a dispersive element. The last one is that microwave dispersive line provides an ultrahigh microwave dispersion approaching several ns <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> over GHz bandwidths. The microwave dispersive line used to implement single-shot microwave pulse compression is theoretically analyzed and verified by a proof-of-concept experiment.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
