Abstract
A radar system that uses a novel multi beam reflector antenna based on the frequency scanning principle is presented. The reflector primary source consists of a frequency multiplexer coupled to eight horn antennas radiating at different frequencies. A prototype of the system working in the X band is demonstrated. It is shown that over a frequency variation of only 2.2%, the main beam direction can be scanned over a sector of 50°. Frequency multiplexing allows an eight‐fold increase in scanning speed compared with purely mechanically rotated antennas. An experiment has been conducted to demonstrate the target detection capabilities of the radar. It is shown that by using a time‐multiplexed combined radiation pattern from mechanical and electrical scanning, it is possible to detect multiple targets beyond the antenna angular resolution limited by its beamwidth. Post processing of the received data from this composite scanning leads to the detection of two targets with angular separation equal to half the antenna beamwidth.

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
