Abstract
A HF sonar performance sea-trial was conducted on the CCGS VECTOR April 8 to 14, 2015 in BC south coast waters. This sea-trial was focused on assessing the limitations to horizontally-oriented HF sonar performance posed by naturally-occurring (e.g. due to white-capping) and ship-wake bubbles. A 90kHz multibeam sonar was operated from the ship against both drifting and towed targets. Forward-looking sonar detection tests were conducted in Sea States from 0 to 5. In low sea-states the drifting targets were routinely observed at ranges up to 550m, but the detection range was significantly reduced under higher sea-states. The aft-looking sonar tests, designed to test target detectability in the ship wake, utilized a towed target at distances from 50m to 500m behind the ship at speeds from 5 to 7knots. Generally the towed target was visible at all ranges except in the close vicinity (<40m) of the stern.

How this classification was reachedexpand
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.
