Abstract
This paper derives two processing methods for optimum SAR/GMTI (Ground Moving Target Indication). The first method, EDPCA (Extended Displaced Phase Center Antenna) extends the well-known DPCA (Displaced Phase Center Antenna) and ATI (Along-Track Interferometry) processing to three or more receive channels. The second method, ISTAP (Imaging Space Time Adaptive Processing), is based on coherent integration of the Post-Doppler STAP (Space Time Adaptive Processing) outputs to increase the target SNR (Signal-to-Noise Ratio).

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
