Abstract

Es wird ein Strahlungsfilter (10) beschrieben, das zur Radarstrahlen-Absorption und zur Dämpfung der IR-Abstrahlung von einem Objekt, wie einem Fahrzeug, Schiff oder einer stationären Einrichtung, vorgesehen ist. Das Strahlungsfilter (10) weist eine elastische Grundschicht (12) und eine elastische Oberflächenschicht (20) auf, die durch Abstandselemente (18) voneinander beabstandet und miteinander verbunden sind. Durch die Abstandselemente (18) ist zwischen der Grundschicht (12) und der Oberflächenschicht (20) ein Hohlraum (22) gebildet. Die elastische Grundschicht (12) weist mindestens zwei Schichtlagen (12a, 12b, ... 12n) auf, die miteinander durch Vulkanisation oder durch Verklebung verbunden sind, und die unterschiedlich relative Dielektrizitätskonstanten besitzen. Die Schichtdicken der Schichtlagen (12a, 12b, ... 12n) entsprechen einem ungeradzahligen Vielfachen des vierten Teiles der Wellenlänge der zu absorbierenden Radarstrahlen.

A radiation filter (10) is described which is provided for radar beam absorption and for attenuating IR radiation from an object such as a vehicle, ship or stationary facility. The radiation filter (10) has an elastic base layer (12) and a resilient surface layer (20), which are spaced apart from each other by spacers (18) and interconnected. By the spacer elements (18), a cavity (22) is formed between the base layer (12) and the surface layer (20). The elastic base layer (12) has at least two layer layers (12a, 12b,... 12n) which are bonded together by vulcanization or by adhesive bonding and which have different relative dielectric constants. The layer thicknesses of the layer layers (12a, 12b,... 12n) correspond to an odd-numbered multiple of the fourth part of the wavelength of the radar beams to be absorbed.
