The SAPPHIRE trial: investigations on angular deviation caused by refraction
Bibliographic record
Abstract
The NATO Panel SET-088 TG-51 has the charter to investigate infrared research topics relating to Littoral Ship Self-Defence. The two main research areas for TG-51 are low-altitude maritime IR propagation phenomenology and ship signature properties. Atmospheric scintillation and refraction prediction models were validated in several trials conducted by different NATO groups. So far most trials were conducted in cold waters. In June 2006, TG 51 performed the SAPPHIRE trial (Ship and Atmospheric Propagation PHenomenon InfraRed Experiment) to collect data in littoral areas under conditions of warm sea temperatures. The location of the trial was the US Naval Research Laboratory's Chesapeake Bay Detachment (CBD) field site on Chesapeake Bay. The objectives of the trial were to validate ship signature models and scintillation/refraction models. In the SAPPHIRE trial, the purpose of FGAN-FOM was to investigate the influence of changing weather conditions on the apparent elevation of a target. Therefore, we set up an IR-camera at CBD overlooking Chesapeake Bay observing a set of lights installed on an Island in 16 km distance. In this paper we discuss and analyse the measured elevations and compare them to the propagation model IRBLEM (IR Boundary Layer Effects Model) by DRDC, Canada.

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.
