Measuring and Modelling the Scattering Parameters of the Wet Radome of the Swiss Weather Radars
Bibliographic record
Abstract
The radome of weather radars can be covered with a layer of water, degrading the quality of the radar products. Considering a simplified setup with a planar replica of the Swiss weather radars’ radome, we measure and model analytically the scattering parameters of the multilayered radome sample, with and without water. The measured reflectance of the dry radome sample is consistent with the one modelled according to the manufacturer specifications. As regards the wet radome sample, for thick layers the distribution of the water complies with the model’s hypothesis of a homogeneous film of uniform thickness. Qualitative agreement is also found for the meteorologically relevant thin layers, but because the water forms droplets, the results can be compared quantitatively only to a limited extent. Simulations with the General Reflector Antenna Software (GRASP) from TICRA complement the study for a more realistic setup with a spherical radome.

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.
