SYSTEM FOR ELECTRO-OPTICAL JAMMING (COUNTERACTING) OF MISSILES WITH INFRARED FLARES

A system for electro-optical jamming (counteracting) of missiles with infrared flares (EOJ), having m radiating elements (m is a natural number: m=1, 2,...) for providing a dimensioned zone of protection (counteracting) of one or group of moving and/or stationary objects (protection objects - PO). The radiating elements are spaced and installed on the outer surface of the PO and turned towards projected threat with providing certain direction of the axis of radiated beams in horizontal plane and vertical one. Inside the body of each radiating element arranged are a light radiation source in the IR-region of the spectrum installed by means of special mounting elements with electrical leads, an optical system which has a lens device for formation of a radiation directional diagrams with angles of beam divergence and in horizontal and vertical planes, respectively. The lens device comprises at least one lens element with a high transmission coefficient of IR-radiation and hermetically installed in the body of the radiating element. An output aperture of the radiating element has elements of external protection, e.g. a nontransparent cover, which is capable of angular and/or linear automatic or semi-automatic displacing. The EOJ has also a control panel (CP) by means of which the operator assigns the operation modes of EOJ, e.g. the radiation mode without modulation or the radiation mode with selected modulation parameters, which are provided due to the modulation of the power supply parameters of radiation sources placed in the body of the radiating elements. The number of m radiating elements depends on the PO characteristics, e.g. type, configuration and dimensions. N part of radiating elemets (n(m) is capable of changing direction of the axis of radiated beams in horizontal plane and/or vertical one depending on the direction of the threat by means of special devices providing, e.g. automatically, their angular and/or linear displacement. In each of m radiating elements p-element assemblies (p is a natural number, p=1, 2,...) are used as the emission sources, in the form matrices, e.g. planar rectangular ones, which are assembled of individual unified hermetic cells made with possibility of removal from the assembly in case of necessary replacement, in optic scheme of which lens elements are used, e.g. spherical lenses or lenses with double curvature placed in fronf of radiation laser diodes of IR range, e.g. with identical or with different radiation wave
