The invention relates to a pyrotechnic active mass which is impenetrable in the visible spectrum, highly emissive in the infrared spectrum and used for camouflage and decoy purposes. As principal ingredients said mass contains red phosphorus and an alkali metal nitrate or mixture of alkali metal nitrates and as secondary ingredients at least one transition metal or a metal-rich compound or alloy thereof, at least one metalloid and a binder.

Pyrotechnic active mass for producing an aerosol highly emissive in the infrared spectrum and inpenetrable in the visible spectrum

The invention relates to a method of producing a screening smoke which is one-way transparent in the infrared spectrum (780 nm-14.0 &mgr;m) and opaque in the visible spectrum. According to the invention a known pyrotechnic screening smoke which is highly absorbent in the visible spectrum (380 nm-780 nm) is generated in the form of an aerosol, pyrotechnic scattered particles between 10 and 100 &mgr;m in size are simultaneously produced in said aerosol, and the resulting two-component smoke is irradiated by an infrared radiation source (spectrum: 780 nm-14.0 &mgr;m) from the smoke producer side.
