Abstract
In this paper, a multi-input multi-output (MIMO) coherent transmit and receive Ground Penetrating Radar (GPR) system, totally software-defined, is presented. all its Tx/Rx parameters can be controlled by the software along with signal processing capability of digitized signals. The system is capable of transmitting and receiving signals over the band of 450 MHz to 6 GHz. To cover this wide band range of frequencies, Three Log Periodic Directive Antennas (LPDA`s) ultra-wideband (UWB) antennas are designed, fabricated and tested. These antennas can be switched using microwave switches. A software-defined and computer-controlled 8-inputs and 32-outputs antenna switching matrix is realized using 1×4 microwave switches. The proposed system can be considered as a non-invasive sensor to detect and image underground targets for various applications that includes detection of land mines, tunnels, bunkers, utility pipes and exploration of natural resources like oil, gas, etc.

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
