Abstract
The papers in this special section focus on space-based synthetic aperture radar (SAR)technology. With the advent of active electronically steerable phased-array SAR antennas equipped with more than one receive channel (i.e., analog-/digital converter) on the most recent generation of commercial/civilian spacecraft, such as RADARSAT-2, TerraSAR-X & TanDEM-X, PAZ, and ALOS-2, relatively mature singlechannel SAR imaging is now rapidly evolving into advanced, multiaperture SAR concepts. The spatial diversity of multiple parallel receive channels can, for instance, be used to discriminate moving objects from the stationary background, to determine the underlying topography of the backscattering terrain, or to measure the large-scale surface motion using single-pass interferometry. The flexible programmability of this newest generation of SAR satellites offers quasi-seamless antenna beamsteering at a rate equivalent to the pulse repetition frequency and, in conjunction with sophisticated array signal processing algorithms, opens up novel radar concepts and capabilities that were not previously possible.

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
