Enhanced WiMAX SAR system equipped with multiple modes
Bibliographic record
Abstract
Widespread use of WiMAX systems has lowered the cost of radio units significantly. We previously proposed a low cost single-mode Synthetic Aperture Radar (SAR) system which took advantage of these low-cost WiMAX transceiver units. However, the imaging swath of this system was limited due to the short length of the cyclic prefix (CP) of WiMAX. In this paper, we propose a multi-mode WiMAX SAR to overcome this limitation. Specifically, we first put forward a design of scan-mode WiMAX SAR, which significantly expands the slant range swath for surveillance and imaging applications. Subsequently, spotlight and squint-mode WiMAX SAR are also proposed to enhance imaging quality. Finally, a windowing scheme on reference data at the receiver is proposed to reduce ghost images in the direction of range. The validity of proposed design is confirmed through detailed simulation results.

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.
