Abstract
A new signal model was developed to replace the traditional one that is based on the go-stop-go assumptions (the go-stop-go model for short) for a wideband synthetic aperture imaging sensor. Using the new model, we traced the time line of the transmitted signal with a given pulse width, round trip time delay of the signal between the sensor and target, and receiving signal with a fixed pulse duration. The spatial displacement of the senor along the time line was calculated. Then, we obtained the two-dimensional spectrum of an individual target and utilized the two-dimensional joint stationary phase method to solve the spectrum. Incorporating the spectrum with available imaging algorithms, we were able to focus targets in a scene. The performance of the model was investigated by analyzing simulated wideband synthetic aperture radar and synthetic aperture sonar data. In the simulations, the imaging algorithms with the new or go-stop-go model were implemented and outputs compared. Results were very promising.

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
