A Methodology for UAV Classification using Machine Learning and Full-Wave Electromagnetic Simulations
Bibliographic record
Abstract
Using micro-doppler signatures is an effective way to classify different types of UAVs, as well as other targets like birds. To generate these datasets, researchers used to conduct campaigns for radar drones’ measurements. However, these measurements are limited to the types of available drones, the used radar parameters, the targets’ range, and the environment these measurements are taken in. In this paper, a new method for simulating these types of datasets is introduced, this new method uses full-wave electromagnetic CAD tools. Radar simulations of five different types of real drones are presented. Using this method, researchers can simulate radar drones’ datasets using different types, sizes, and design materials of drones, they also can change the used radar parameters, detected range, targets speed, and rotors RPM for rotary drones. A 77 GHz FMCW simulated radar is used to generate the required dataset for classification purposes. Finally, a CNN algorithm is used to classify the five types of simulated drones, the accuracy of the used algorithm is better than 97%.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
