Abstract
Bistatic models of the ocean clutter in the context of pulsed high-frequency ground wave radar (HFGWR) operation have previously been developed. Several new features, distinct from earlier monostatic developments, appear as products of the analysis. The question that must be addressed is "will the characteristics of the theoretical clutter models be visible in real-life data collected from the ocean surface?" One of the major considerations in answering this is the development of an appropriate noise model. Such a model for the noise spectral density as it relates to the pulsed HF radar operation is considered here. The analysis proceeds on the assumption of an ideal, externally noise limited, system. The aliasing due to noise undersampling is seen to be an integral part of the model. Statistical stationarity is assumed throughout.

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
