Abstract
This paper presents a new swath bathymetric sidescan sonar concept that extends the single angle-of-arrival measurement technique used in interferometric sidescan to multiple angles-of-arrival. The new sonar concept utilizes a small array of vertically stacked sidescan transducer elements and affords high resolution 3D imaging and mapping of underwater geometries difficult to address using simple interferometry. The focus of the paper is the presentation of 3D sector-scan and sidescan results obtained using a prototype six element 300 kHz sonar. Results are presented for both target imaging and bottom mapping experiments.

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
