An engineer at Research Support Instruments is working with the U.S. Air Force to develop a project called the Microwave Ionosphere Reconfiguration Ground based Emitter, codenamed Mirage. Now this isn t creating tornadoes or wind storms to wreak havoc, it is modifying the ionosphere to disrupt enemy communications and to help ours.
The ionosphere is an electric band in the upper atmosphere. The Mirage project would station a microwave transmitter on the ground then launch a small rocket into the atmosphere that would release plasma throughout the ionosphere. The plasma would modify the number of electrons within a selected area of the ionosphere, thereby creating a virtual communications barrier. This would benefit the military in two ways: the enemy's communication with satellites would be hindered, and the highly charged ionosphere would allow for better radar relays on our side. The initial phase of the project is complete.
