Subject of research. The paper considers the approach to generation of pulse optical jamming signals in broad range of wavelengths aimed to suppress visual optical and electro-optical channels of surveillance equipment operating in different spectral bands. Method. The high-intensity emission optical source was created utilizing compact cermet case short-arc high-pressure xenon lamps with internal reflectors. Optical emitter with multiplication of lamps was used in order to attain the values of energy density above the specified criterion levels at the distances of suppression. Main results. The emitter was constructed for visual-optical jamming in the spectral range of 0.35-2.5 μm with maximum light intensity of 95∙105 cd and irradiance of 120 W/m2 at 10 meters. The low-frequency modulation varies from 5 to 15 Hz while the high-frequency modulation of low-frequency pulses is kept constant at 5 kHz with 60 % modulation depth. The beam width can be mechanically switched from 6 to 15°. The emitter is embodied in all-climate type of enclosure and can be operated from –40 to +50 °C and air humidity up to 98 %. Practical relevance. Implementation of cermet case short-arc high-pressure xenon lamps with fixed integrated reflector provides an opportunity to construct compact high-power emitters of pulsed optical signals. The lamps are explosion-proof and not prone to devitrification and depressurization. The emitters utilizing the lamps with internal reflectors do not require in-service adjustment, have high reliability and durability. The emitter can be configured with the lamps of variant optical power in order to satisfy the electrical power availability of delivery vehicle of all kinds.
