Defense shield deceives satellites.
:::: Inspiration from Nature//
Black stork (Egretta Gularis) can see the reallocation of fish in the water by removing the refraction of light.
:::: Problem Statement//
The drone has proven to be one of the deadliest military technologies of this era. Its role in the war on terror has brought this technology a formidable reputation among militaries around the world. However, an unmanned plane is barely the tip of the iceberg. The main technology works behind it- or rather above it. Drone strike depends upon satellite imaginary which cannot easily be fooled because it has multiple vantage points besides deadly precision. The satellites- equipped with infrared sensors- no longer depend on visual feed and are able to locate targets several feet underground- much like in space archeology. So the question is, can we fool a drone technology by fooling its eyes in the sky.
:::: Nature Review//
Reef heron and black stork (Egretta Gularis) demonstrate a mind-boggling hunting technique. These birds locate the actual position of fish in water- nullifying its refractive index- with the angle and tilt of their head. This ability to overcome the refraction of light can become the basis for a more advanced defense strategy against drones. Please see the technical review for more details.
:::: Technology Review//
Stealth technology relies on the reflection of waves through planar surfaces (or distortion of the image through refractive planes). The concept has an under-water application as well (Seismic Refraction at sea, for instance). We need to create a reverse situation where highly advanced satellite imagery can be deceived by a change of medium between satellite and location. Like a laser, we need to project an augmented reality of infrared (and overlapping particle-waves). So, the AR projection is registered by sensors of all satellites from all angles.
:::: Nature Gadget//
Real coordinates of a target facility are concealed before the enemy eyes in the sky.
The given area is projected above accurately, as an umbrella of holographic data (having infrared, thermal, visual, UV, and electromagnetic information). But the coordinates of an important facility in the area are refracted in its holographic imagery. Satellite-controlled drone targets fake coordinates.
An augmented screen is projected (8) around a large area over a building that needs hiding from a satellite. The screen copies 3d textures under it (18) and projects them (16) live after manipulating their refractive indexes (15, 19). It overlaps visual output with the radio (22) and thermographic mapping (24) which convinces a military satellite (as well as the moving drone) that the building exists at a certain (wrong) location. If one drone strike gets misguided this way, it would give time for the people in the real building to escape (like fish in water).
