The radar screen should have been a promise of order: aircraft where they belonged, transponders chirping, controllers free to think about separation and safety instead of mystery. But again and again, from the strange returns over Washington in 1952 to the Navy’s Tic Tac encounter, from Chinese spy balloons to the recent drone panic over the Northeast, the sky has forced a more unsettling question onto the machines built to police it. Not whether every UFO is an alien craft, but whether modern radar—designed to tame chaos by filtering out clutter, noise, and irrelevance—can sometimes tidy the picture so well that it hides the truth. A UFO, in the strictest sense, is only an object we have not identified yet. It may be adversary surveillance, atmospheric mischief, airborne trash, or something harder to name. The real drama is that in a crowded age, a clear screen can feel like certainty even when it is only an edited version of reality.

Scientific sensing is entering a new era. Where older instruments relied on springs, mirrors, coils, and bulk mechanical motion, a new generation of platforms now uses atoms, spins, photons, superconducting circuits, and engineered quantum materials as its reference frame. That shift matters because it opens the door to measurements that are not only more sensitive, but fundamentally different in character: gravity can be read through atomic phase, magnetic fields through spin precession, radiation through cryogenic energy deposition, and near-field forces through quartz resonators and nanoscale probes. For researchers interested in subtle gravitational, electromagnetic, quantum, or even purportedly anomalous phenomena, these sensor families offer a fascinating landscape that ranges from mature field instruments to highly experimental platforms at the frontier of physics.

Greg Cathcart discusses the scientific, engineering & technical challenges involved with detecting “anomalous transit” by UAP, and explores the detection, perception, and bias inherent in Unidentified Aerial Phenomena (UAP) investigations.

Gene Greneker discusses the history of UAP radar tracking, explains why filters make UAP invisible to airports, and describes DIY passive radar as the "next step" in UAP radar detection.

Tim Ventura summarizes a multimodal approach to Unidentified Aerial Phenomena (UAP) detection, advocating for the combined use of 14 methods for more reliable analysis than single-source data. These methods include active and passive radar, microwave and electromagnetic spectrum detection, X-ray/gamma ray spectroscopy, magnetometry, optical imaging (including FLIR and UV), gravitational lensing analysis, radiation detection (Geiger counters, scintillators, neutrino detectors), audio detection, and sonar.

David Hooper showcases his work on a multispectral UAP detection system at the UAP Hackathon 2025 in San Francisco. Hooper's innovative gimbal tracking system integrates various cameras (UV, visible, IR) and a custom pan-tilt head with a slip ring, overcoming limitations of standard security cameras. The system aims for consumer-friendly plug-and-play integration, utilizing readily available components like common camcorders.

Is evidence of UFO warp drives hidden in plain sight? Chad Wanless discusses UFO physics & detection of Alcubierre Drive signatures from his book, “Hidden in Plain Sight: Evidence of Exotic UFO Propulsion”. In this presentation, Chad provides a detailed overview of the physics involved with Alcubierre Drives propulsion, and cites examples of warp-signatures detected in UFO photos & video, which includes relativitic effects such as gravitational lensing, changes in apparent temperature around the craft, and the formation of vapor cones in front of UAP from spacetime compression.

Mitch Randall is the CEO of Ascendant AI and innovator behind the SkyWatch Passive Radar UAP tracking system, developed for for Unidentified Aerial Phenomena (UAP) detection. Mitch has Masters Degrees in both Electrical Engineering & Physics, and has a long history in scientific instrumentation and radar - dating back to 1984. His experience includes roles at the National Center for Atmospheric Research (NCAR), along with dozens of key inventions in radar technology widely used across industry. Skywatch was developed through the Galileo Project and hopes to detect UAP using reflected signals as an alternative to traditional radar technology.
