GEAR FORMING MODULATED JAMMING TO OPTOELECTRON DEVICES

摘要

equipment protecting objects against optoelectron devices. SUBSTANCE: gear forming modulated jamming is made of two cylinders positioned coaxially in whose generating surfaces are cut slits permeable to infrared radiation. One of cylinders is mounted for rotation around radiator of infrared radiation pulses which is placed inside cylinders along central axis. The cylinder presents combination of regular structures formed by slits arranged along generating line of cylinder and irregular structures formed by irregular straps. Irregular straps come in the form of reflecting screens. Gear is supplemented with spectral filter whose spectral filtration range coincides with spectral range of radiation of protected object. Mirror reflectors are positioned in addition perpendicular to longitudinal axis of cylinders. Radiator is manufactured in the form of ellipsoid of revolution turning about longitudinal axis to ensure uniform distribution of radiation density in space. EFFECT: suppression of optoelectron devices both with amplitude-phase and frequency-phase modulation without re-tuning of jamming station and its placement outside limits of protected object, substantial decrease of energy consumption for suppression of noise and increased reliability of jamming. 6 cl, 4 dwg
