Abstract
In this paper, a moving spherical target in a Pekeris waveguide is considered. The classification of a target from its free space echo has been previously studied by many authors. In a waveguide, the received echo results from the coherent interference of the various multipaths incident upon and scattered from the target. When the position of the target in the waveguide is imprecisely known, the echo classification problem is more difficult. In addition, if the target is moving with an unknown radial speed, this further complicates the problem. In this paper, we consider a single omnidirectional transmitter and a single receiver and investigate the estimation of the material, geometrical, positional, and dynamical parameters of the sphere from the received echo. We use a simple simulated annealing approach to investigate the parameter estimation. We also consider various two-dimensional cost-function surfaces to illustrate the uncertainties in the parameter values.

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
