Method for masking fixed or mobile targets, in particular military objectives, against location by electromagnetic radiation located in the wavelength range from 1 mm to 1 m, emitted by a search radar, by the production and arrangement of a gaseous, fog or liquid shield body in front of the target, around it, or on it. In order to generate the screen body, mineral and / or organic, gaseous and / or liquid chemical compounds are used, which a) absorb, as a result of the excitation of the rotations of the molecules, said electromagnetic radiation and then emit polychromatic electromagnetic radiation diffuse and b) consist of at least three unaligned atoms per molecule, and / or c) exhibit a nearly continuous rotational absorption spectrum, and / or d) have a dipole moment of 0.1 to 10 debye, of preferably at least about 2 debye, and / or e) have a moment of inertia of 15 x 10-40 to 1000 x 10-40 g.cm2. Suitable compounds include halocarbon and halohydrocarbon compounds, such as Frigènes and Freons. |
