Abstract
With the help of in-water experimentation data, we study: (1) the merits and limitations of two major classes of Active Sonar Systems, namely, Pulse Active Sonar (PAS) and Continuous Active Sonar (CAS), with the Doppler-Tolerant Linear Frequency Modulation (LFM) waveform; and (2) the merits and limitations of Doppler-Tolerant LFM and the Doppler-Sensitive SHAPE waveforms with CAS. Throughout the study, Matched Filter (MF) is used as the receiver design. The strong delay and Doppler spread direct blast and poor MF performance in noisy environments warrant us to introduce processing techniques which enable receivers to produce accurate range estimates.

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
