Abstract
The dynamic range of radar receiver chains is a critical concern in practical scenarios due to the significant variation in power levels between backscattered signals from desired targets and surrounding clutter. High Radar Cross Section (RCS) clutter echoes can easily overwhelm the receiver chain, particularly when the detection system is optimized for low RCS targets, such as UAVs or birds. This paper explores the potential enhancements offered by TX Digital Scanning Beamforming compared to conventional MIMO techniques. It introduces a straightforward model to predict these benefits, supported by an experimental validation using a Texas Instruments (TI) FMCW Cascade Radar platform operating in TX Beamforming mode, offering valuable insights into the achievable performance improvements.

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
