Appendix C — Existing Detection Systems
June 15, 2026 · 1 min read
Abstract
Existing surveillance, sensing, and reporting systems with latent anomalous-event detection capability relevant to UAP analysis.
| System | Data type | Relevance |
|---|---|---|
| Doppler Radar Network | 160 S-band weather radars; reflectivity, velocity, spectrum width; publicly archived | Detects non-meteorological airborne returns; provides atmospheric baseline; nationwide continuous coverage enables retroactive analysis |
| satellite constellation | 16-band visible and imaging; full-disk every 5–15 minutes | Establishes environmental context concurrent with reported events; helps rule out meteorological explanations |
| Vera C. () | 8.4 m survey telescope; six optical bands; entire visible sky every three nights; full operations expected 2026 | Automated transient and anomaly alerts; / pipelines adaptable for anomalous-object detection in near-Earth or cislunar space |
| FlightRadar24 / OpenSky Network | flight tracking; real-time and historical | Identifies cooperative air traffic near a reported event; objects in radar data absent from ADS-B may warrant investigation |
| MarineTraffic / Networks | Global vessel tracking; real-time and historical | Rules out maritime vessel misidentification for coastal and over-water events |
| Radiosonde Archive | Vertical atmospheric profiles from 2,800+ stations globally | Identifies weather balloon launches correlatable with reports; atmospheric profiles help assess radar propagation anomalies |
| Confidential voluntary pilot and ATC safety reporting; 1.94 million cumulative reports over 47 years; approximately 100,000 per year | Recommended in the 2023 NASA [55] as a channel for systematic pilot reporting within a trusted, destigmatized framework |
