High-power pulsed light and acoustic radiation and possibilities of their application

Summary form only given. Development of pulsed light and acoustic radiation sources, based on high-power electric discharges in the air at atmospheric pressure is made in VNIIEF. Studies of their characteristics are performed. High values of light radiation luminosity and acoustic pulse intensity, simplicity of radiators design, their ability to work both in monopulse and frequency regimes allow to create alarm and warning systems for different purposes. These sources can be used in sea and river vessels in the regimes of normal and emergency applications. Also they can be used for attracting the attention of other vessels, coast and rescue services, to prevent vessel collision in bad visibility conditions. Visual observability of light pulses and good audibility of sound ones at long distances and the possibility of essential multiplication of these distances with the help of special equipment will allow to realize systems of coded information transmission between vessels with coast services in radio communication disability and in other cases. Sources of high-power light pulses can be used in beacon operation of different ranges of operation for visual or hardware detection of aircraft location on flight route using light markers, located on the ground. The most preferable areas of this beacon usage are aircraft landing in bad visibility conditions or in emergency. Birds, animals and people, being in a take-off strip zone can affect flight safety. Because of the limited possibilities and uniform usage of bird scaring systems, birds adapt to them. The complex usage of powerful light and acoustic actions, producing "shot" effect, allows to solve the problem successfully. Propagation conditions and different registration methods of high-power pulsed light radiation were also studied at the experiments performed in VNIIEF.
