Abstract
A highly-directional FPGA-based broadband beam former is proposed using a novel 3D IIR plane-wave digital filter. This filter acquires the 3D spatio-temporal input signals from spatially-rectangular arrays of sensors that are scanned by only one time-multiplexed A/D converter. The proposed architecture employs a novel scanned-array 3D parallel vector-processor (VP), clocked at 80 MHz, and has the potential to achieve real-time broadband plane-wave filtering on a single low-cost integrated circuit at spatial frame-rates of 19 kHz over a 64 by 64 spatial broadband sensor array.

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
