Abstract

Die Erfindung betrifft eine Wirkmasse für ein beim Abbrand der Wirkmasse spektral strahlendes Scheinziel mit einem in der Wirkmasse verteilten Zusatzstoff, der ein Verhältnis von einer Intensität einer beim Abbrand der Wirkmasse emittierten Strahlung im Wellenlängenbereich von 3,7 bis 5,1 µm zu einer Intensität einer beim Abbrand der Wirkmasse emittierten Strahlung im Wellenlängenbereich von 1,9 bis 2,3 µm erhöht, wobei die Wirkmasse einen Kohlenstoff- und Wasserstoffatome enthaltenden Brennstoff und ein Sauerstoffatome enthaltendes Oxidationsmittel für den Brennstoff umfasst, wobei die Menge des Oxidationsmittels so bemessen ist, dass sie nicht für eine vollständige Oxidation des Kohlenstoffs ausreicht, wobei der Zusatzstoff ein in Form von Partikeln vorliegender eine Redoxreaktion katalysierender Katalysator ist.

The invention relates to an active mass for a spectrally radiating decay target when burned with an additive distributed in the active mass, the ratio of an intensity of the emitted radiation during combustion of the active material in the wavelength range of 3.7 to 5.1 microns to an intensity of when the effective mass burned off radiation in the wavelength range of 1.9 to 2.3 microns increased, wherein the active material comprises a carbon and hydrogen atoms containing fuel and an oxygen atom-containing oxidant for the fuel, wherein the amount of the oxidizing agent is such that they is not sufficient for a complete oxidation of the carbon, wherein the additive is a particulate present in a redox reaction catalyzing catalyst.
