Abstract
The RADARSAT Constellation Mission (RCM) is a Canadian SAR mission consisting of three C-band SAR satellites. RCM is currently being designed by a Canadian industrial team led by MacDonald-Dettwiler and Associates (MDA) under contract to the Canadian Space Agency. The emphasis of this paper is on providing a description of those capabilities of RCM that are unique or innovative. These unique or innovative capabilities include a constellation optimized for coherent change detection (CCD), a compact polarimetry mode, special imaging modes optimized for ship detection, and capabilities to support ocean current and ocean wind estimation. To support CCD, the system design includes maintaining the satellites in a narrow orbital tube, a tight requirement on azimuth antenna pointing control, and ScanSAR burst timing calculated from on-orbit spacecraft location data. For compact polarimetry, a capability to transmit circular polarization and receive H and V simultaneously is part of the design. For ship detection, innovative ScanSAR modes are used with a large number of beams and variable resolution and looks designed to optimize ship detection across a wide swath. In order to support ocean current and ocean wind estimation, a Doppler grid is included in the product meta-data.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
