Abstract
The detection performance of a high frequency surface wave radar (HFSWR) system is primarily limited by clutter, especially ionospheric clutter. Therefore, in order to analyze and/or simulate the capabilities of an HFSWR system a model for the clutter is required. This paper develops and tests a new radio wave propagation theory to model ionospheric clutter. The model is based on path integrals of ray tracing equations which predict the phase power spectrum of clutter due to irregularities in the plasma. This power spectrum is then used to simulate three-dimensional space-time-range radar data cubes. The accuracy of the model is tested by comparing the simulated data to measured data cubes. As an application, the data is then used to evaluate the performance of the newly developed fast fully adaptive processing scheme to mitigate clutter.

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
