Abstract

fetched live from OpenAlex

The design of RADARSAT-2, scheduled for launch in 2007, has been driven by the needs of the global Earth observation markets. The RADARSAT-2 Synthetic Aperture Radar (SAR) antenna is a state-of-the-art active array designed, built and tested by MDA in its Montreal facilities. The large 15 m times 1.4 m antenna is comprised of 512 subarrays that are each connected to a Transmit/Receive (T/R) module. High performance electronics provide power and control to the T/R modules. These units along with Radio Frequency (RF) power divider networks and harnesses are mounted on four integrated aluminum panels that are deployed on a Carbon Fiber Reinforced Plastic (CFRP) extendable support structure. The lower level units were built and tested before being integrated to the antenna. The antenna went through acceptance testing that included environmental and near field range tests. Good correlation was obtained between the predicted and the measured performances. The antenna met all expectations and at the time of writing this paper, has been integrated to the spacecraft.

Full frame distilled prediction

Teacher imitation

Not 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.
