Abstract

fetched live from OpenAlex

The purpose of this thesis is to design a solution to the problem of random and fast movement of a ground platform which normally prevents the use of a high gain, pencil beam antenna.Such a problem has prevented the development of a truly mobile ground radar (i.e useable as a vehicle is moving, in contrast to the current concept of mobile ground radar, which translates into a ground radar that can be easily moved between static operation sites.)In response to this requirement, a self-stabilizing switched offset reflector antenna was designed.Through the use of accelerometers and position filtering, the antenna constantly switches its beam in order to maximise directivity in the intended direction.As a proof of concept, a 10 GHz, single dimension dish was built and tested in laboratory.The results confirmed that the concept is viable and would open enable not only truly mobile radar, but could potentially greatly improve mobile satellite communications by allowing never seen before antenna gain on ground vehicles.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
