Validation of direct and indirect far-field antenna measurements at Memorial University's electromagnetic facilities
Bibliographic record
Abstract
Indoor direct measurement of antenna far-field radiation patterns requires that the antenna be placed far away from the source and data be collected in a controlled environment, i.e., expensive large size anechoic chambers. Data from near-field antenna measurements can also be used to calculate the far-field radiation patterns, which are indirect far-field measurements. A low cost near-field/far-field antenna measurement system and a 4 m/spl times/2.5 m/spl times/2.5 m anechoic chamber have been built at C-CORE, Memorial University of Newfoundland (MUN). The two systems provide significant flexibility in antenna test capabilities. This paper describes this low cost indirect near-field/far-field measurement system. The comparison with data obtained from direct far-field measurement inside the anechoic chamber indicates the validity of both measurement techniques.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
