Abstract
The spectral amplitudes of High-frequency (HF) radar signals backscattered from the ocean are known to be a Rayleigh distributed variable. The mean radar Doppler spectrum forms the basis for the extraction of sea-state parameters. Conventionaly, the mean spectrum is obtained by averaging the power of several Doppler spectra, a process which utilizes only the amplitude information of the sea echoes. The phase information is assumed to be meaningless. An assessment of a complex-value averaging scheme for HF radar systems is attempted through a simulation-based study and a field-data comparison with measurements from a moored current meter for a year of time. Results show that, although the power-averaging method outperforms the complex-value averaging for every simulated case, when field data are used, the RMS difference of the power-averaging method is significantly higher than that of the complex-value averaging, when the time series is long and extra smoothing is not ulized.

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
