Abstract
Beamformer is an important part of the wideband radar systems. An approach to achieve the high sampling rate required in such systems is to use efficient hardware implementations. This paper presents a speed optimized systolic arrays for implementation of the wideband beamformer using nested arrays, 2-D filters, and multirate techniques. The implementation structures of the beamformer basic building blocks are designed based on systematic methodology and implemented using the field programmable gate array (FPGA) platform targeting Basys- 3 development board's Xilinx Artix-7 (XC7A100T) FPGA chip. A single channel of the beamformer was chosen for the implementation to confirm the correct functionality of the FPGA architecture. The implementation performance is tested in terms of effect of errors due to finite word-length arithmetic.

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
