A dynamic STC attenuation strategy based on environmental perception
Bibliographic record
Abstract
Abstract The fixed static STC suppression strategy is often applied in project practice. There is frequently an issue where clutter procession algorithms fail to swiftly adapt to environmental changes, leading to an increased false alarm rate in radar systems, which significantly impairs the normal detection of targets and, consequently, directly undermines the tactical effectiveness of air defense operational command systems. The paper discusses that signal processing is used to process the data before and after the attenuation of STC in the full range section respectively, and the attenuation value in the full range section is quantified according to the minimum scale. After multiple iterations, an attenuation benchmark is set for different range segments to enable dynamic selection of STC (Sensitivity Time Control) attenuation strategies. This enhances the adaptive and rapid matching capabilities of clutter suppression strategies to changing environments, achieving a dynamic balance between target detection probability and false alarm rate. Ultimately, it realizes the radar’s clutter environment perception and adaptive clutter processing capabilities, enabling the radar to maintain superior target detection performance in cluttered or interfered environments.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
