Navy's Plasma-Based IR Signature Patent: A Defensive Countermeasure Unlikely to Explain Navy UFO Sightings
To the point
A Navy patent describes using laser-generated plasma to mirror infrared glow or draw 2D/3D images in midair to mislead heat-seeking missiles, framed as a defensive countermeasure, and while some speculate it could explain Navy UFO sightings, radar and other sensors showing solid high-altitude objects argue against that, since such effects would degrade with distance and require close viewing, though other nations might pursue similar ideas.
