Abstract
The detection and classification of Unmanned Aerial Vehicles (UAVs) are disturbing challenges within contemporary radar systems, wherein the physical characteristics of UAVs, including their size and Radar Cross Section (RCS), exert a substantial influence on radar’s detection capabilities. Smaller UAVs, characterized by reduced RCS values, often escape radar detection. In response to these challenges, this study introduces an efficient radar signal processing technique based on beamforming, termed Range-Doppler Integration while Steering (RDIwS). RDIwS significantly enhances the Signal-to-Noise Ratio (SNR) associated with UAVs, resulting in an increased detection probability and classification accuracy for these UAVs. Importantly, the RDIwS approach demonstrates superior performance to traditional Multiple-Input Multiple-Output (MIMO) methods and established beamforming-based techniques, showcasing its potential to significantly advance UAV detection and classification across various operational contexts. For four targets located at different angles and distances scenario, and at -30 dB SNR and false alarm probability of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-5</sup> , the RDIwS beamforming-based method achieved a detection probability of 75% compared to 5% for steering-only beamforming, and no detection for MIMO radar case.

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
