Abstract

fetched live from OpenAlex

In the present investigation, the impacts of antenna field of view (FOV) on the accuracy of machine learning (ML) models utilized for the classification of various unmanned air vehicle (UAV) types were systematically explored using full-wave electromagnetic simulation software. Initially, similar to many state-of-the-art works, an ML algorithm was meticulously trained under a particular condition where the relative angle between the UAVs and the antenna was kept at 0 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$^{\circ}$</tex-math> </inline-formula> , yielding an accuracy of 96.5%. In contrast to the common practice, the trained ML model was subsequently subjected to testing at varied relative angles, spanning from 20 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$^{\circ}$</tex-math> </inline-formula> to 90 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$^{\circ}$</tex-math> </inline-formula> . Observational outcomes delineate a decrease in ML classification accuracy with an increase in the relative angle between UAVs and the antenna. Next, this study investigates the impact of utilizing multiple-input-multiple-output (MIMO) radar system for classification. The results indicate enhancement of UAV detection and classification efficacy when contrasted with a single-input-single-output (SISO) radar system, at 80 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$^{\circ}$</tex-math> </inline-formula> , an accuracy of 60% for the MIMO antenna compared to 13% for the SISO antenna. To corroborate the results obtained by utilizing full-wave electromagnetic simulation software, a series of experimental laboratory measurements were undertaken. The empirical measurements were found to yield comparable ML accuracy, at 80 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$^{\circ}$</tex-math> </inline-formula> , an accuracy of 38% for the MIMO antenna compared to 1% for the SISO antenna. This work underscores the paramount versatility achieved through invoking full-wave electromagnetic simulators alongside ML algorithms and the respective possible impact on standard practices when it comes to developing next-generation MIMO radar systems for UAV classification.

Full frame distilled prediction

Teacher imitation

Not 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.
