IR-radar image generator to provide a decoy and associated method of operation

摘要

A method of forming a mobile combined infrared (IR)-radar decoy to protect the Navy's above-water objects by diverting IR-radar-guided missiles uses a moving jet of hot exhaust gases from an air-jet engine installed nearly horizontally on a small boat what speeds it forward. Ionization of the hot exhaust jet is accomplished by the injection of a liquid alkali metal, which when sprayed into the combustion products, burns to form an electrically conductive spray-plasma. This process occurs due to the interaction of the electrostatic Coulomb forces generated by the bound electrons on the alkali metal droplet surface with the free electrons in the vapor shells of the burning droplets. This interaction expels the free electrons into the united flame zone. The apparatus for implementing this method comprises a system for masking any visible emissions from the plasma and neutralizing the alkaline blowout into the air and water.

1. A method and mobile apparatus for forming a combined IR-radar image of a false target to cause infrared-radar-guided missiles to deviate from their above-water target. The method comprises the following steps: first, the formation of a moving jet of hot exhaust gases from an air-jet engine to create a jet that is geometrically similar to the object being protected. Next, the hot exhaust jet is ionized through the injection of a liquid alkali metal into the jet, which, when atomized, heats to sufficient temperatures for self-ignition, followed by the vapor-phase burning of the metal droplets, which form an electrically conductive spray-plasma through the interactions of natural electrostatic Coulomb forces generated by the fixed electrons on the droplet surfaces with the free electrons in the droplet vapor shells, which are discarding into the united electrically connected flame zone.
