Disambiguation
Refers to the detection, analysis, and forensic significance of exhaust signatures (thermal, visible, chemical) as evidence in aircraft identification and UAP investigation—distinct from general propulsion systems.

Concept
The detection, analysis, and forensic use of exhaust signatures (thermal, visible, chemical) to identify aircraft, assess propulsion systems, and distinguish conventional from anomalous phenomena in aviation and UAP investigation.
A detecção, análise e uso forense de assinaturas de exaustão (térmica, visível, química) para identificar aeronaves, avaliar sistemas de propulsão e distinguir fenômenos convencionais de anômalos em investigação de aviação e UAP.
