Abstract
A method for production of an infrared area emitter which can be used for defense against guided missiles with infrared homing heads, for example for ships. According to the invention, an aerosol cloud which is emissive in the infrared range is produced by the reaction of a first primary aerosol composed of an aqueous solution of an electron acceptor with a second primary aerosol composed of an aqueous solution of an electron donor in order to produce the infrared area emitter. The use of primary aerosols such as these leads to emission at 3-5 and 8-14 μm, and does not produce any visual signature either.
Claims19
A method for the production of an infrared area emitter comprising:
- providing a first primary aerosol including an electron acceptor and a second primary aerosol including an electron donor;
- and
- reacting the first primary aerosol and the second primary aerosol to provide an aerosol cloud which is emissive in the infrared range.
A method for the production of an infrared area emitter comprising:
- providing a first primary aerosol including an electron acceptor selected from phosphoric acid and sulphuric acid and a second primary aerosol including an electron donor selected from an alkaline metal hydroxide, an alkaline metal carbonate, an alkaline metal hydrogen carbonate and mixtures thereof;
- and
- reacting the first primary aerosol and the second primary aerosol to provide an aerosol cloud which is emissive in the infrared range with emission bands in the wavelength from 3 to 5 and/or 8 to 14 microns, said aerosol clouds does not produce any visual signal.
An infrared area emitter comprising an aerosol cloud that is emissive in the infrared range, said aerosol cloud is a reaction product of a first primary aerosol and a second primary aerosol, wherein said first primary aerosol is an electron acceptor and the second primary aerosol is an electron donor.
