Abstract

fetched live from OpenAlex

The high-frequency radar cross-section (RCS) for ocean surfaces with arbitrary wave heights is presented. By removing the height restriction of the ocean surface, a new form of the first-order electric field is obtained, which in turn is used to derive the RCS at arbitrary wave heights. A new correction term for the first-order is derived, with previously-derived first-and second- order RCSs being preserved. Through simulation it is shown that the new term impacts small Doppler frequencies of the total RCS at high sea states. The present work can contribute to improving target detection and wave direction estimation at high sea states.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
