System Study of Constraints for the Creation of UAP Electromagnetic Signature Optimal Detection Systems

Brief

Using established radiometric and signal-detection frameworks (Neyman-Pearson or equivalent), the paper constructs detection probability models for hypothetical UAP EM signatures in both the optical and radio-frequency domains. The analysis treats the problem as a systems engineering optimization: for a given required probability of detection and maximum tolerable false-alarm rate, it maps how sensor aperture and integration time constrain achievable detection range. No empirical UAP data are tested against the models; the contribution is the parametric design envelope rather than a detection claim. The work is notable for being presented at AIAA Aviation 2023, a mainstream aerospace engineering venue, signaling institutional normalization of UAP as a legitimate sensor-design target.

Key points

• The paper derives detection probability (Pd) as a function of range, treating UAP EM emissions as a signal-in-noise problem governed by the same radiometric chain used in radar and electro-optical system design.p.3
• Sensor aperture and integration time are shown to trade against each other in extending detection range: doubling aperture area or quadrupling integration time each yield equivalent SNR gains for unresolved point sources.p.5
• False-alarm rate (Pfa) constraints significantly compress the usable detection threshold, particularly in high-clutter optical environments, a key practical limit on fielded system performance.p.6
• Both optical (broadband and narrow-band) and RF bands are analyzed as candidate detection modalities, with the optimal band depending on the assumed EM emission profile of the target.p.4
• The analysis frames UAP detection as a classical systems engineering problem, explicitly importing design methods from defense electro-optical and radar communities rather than proposing novel physics.p.2
• The paper identifies integration time as a double-edged parameter: longer dwell improves sensitivity but degrades temporal resolution needed to characterize fast-moving anomalous objects.p.7
• No specific UAP emission spectrum or brightness temperature is assumed as ground truth; the models are parameterized across a range of source irradiance values to bracket the unknown.p.4

Most interesting

• Presentation at AIAA Aviation 2023, the flagship annual conference of the American Institute of Aeronautics and Astronautics, marks one of the first times UAP detection system design appeared as a formal paper in a peer-reviewed aerospace engineering program.
• The paper's framework is entirely agnostic to UAP origin: it applies the same detection equations used for ballistic missiles, aircraft, and satellites, treating UAP simply as uncharacterized EM emitters.
• Integration time emerges as a critical tension point: the sensitivity gains needed to detect distant or dim objects conflict directly with the short dwell times required to track high-velocity anomalous phenomena.
• By importing Neyman-Pearson decision theory, the paper implicitly sets a falsifiable design bar, a proposed detection system either meets the derived aperture/range/Pfa requirements or it does not, independent of any belief about UAP nature.
• The dual-band (optical + RF) treatment acknowledges that UAP signatures observed historically span both domains, but no single sensor architecture is shown to optimally cover both without mission-specific trades.
• The conference-proceedings format means the work passed AIAA technical-committee review, lending it a level of peer scrutiny uncommon in UAP-adjacent literature.
