Abstract

FIELD: passive radiolocation. SUBSTANCE: invention relates to radio engineering means of passive radiolocation of sources of pulse electromagnetic radiation and can be used to measure location of atmospheric at distances 300-1500 km in meteorology and civil aviation for increase of flight safety. Electromagnetic signal of atmospheric is received by vertical electrical rod aerial and by two horizontal magnetic aerials oriented orthogonally. After preliminary integration of magnetic signals all three components of atmospherics are amplified and filtered within wide and similar frequency band, bearing to atmospherics source is determined by relation of correlations between electric signal and each of magnetic signals deeply and symmetrically limited. Apart from this additional signal corresponding to projection of horizontal magnetic field on to direction of signal propagation is determined. Range to atmospherics is found by time interval between coming of electric and additional magnetic signals. Generated coordinates are displayed on screen of indicator of location of atmospherics source. EFFECT: increased precision and reduced time of measurement of location of atmospherics.

Изобретение относится к радиотехническим средствам пассивной локации для определения местоположения источников импульсного электромагнитного излучения и может быть использовано для измерения местоположения грозовых разрядов на расстояниях 300-1500 км в метеорологии и в гражданской авиации для повышения безопасности полетов. Электромагнитный сигнал грозового разряда (атмосферик) принимается вертикальной штыревой электрической антенной и двумя горизонтальными, ортогонально ориентированными магнитными антеннами, после предварительного интегрирования магнитных сигналов все три компоненты атмосферика усиливаются и фильтруются в широкой и одинаковой полосе частот, по соотношению корреляций между глубоко двухсторонне симметрично ограниченным электрическим и каждым из магнитных сигналов определяется пеленг на источник атмосферика, кроме того определяется дополнительный сигнал, соответствующий проекции горизонтального магнитного поля на направление распространение сигнала, по интервалу времени между приходом электрического и дополнительного магнитного сигналов определяется дальность до грозового разряда. Получаемые при этом координаты отображаются на экране индикатора местоположения источника атмосферика. Предлагаемый способ позволяет повысить точность и уменьшить время измерения местоположения грозовых разрядов.The invention relates to radio-electronic means of passive location for determining the location of sources of pulsed electromagnetic radiation and can be used to measure the location of lightning discharges at distances of 300-1500 km in meteorology and in civil aviation to improve flight safety. The electromagnetic signal of a lightning discharge (atmospherics) is received by a vertical whip electric antenna and two horizontal, orthogonally oriented magnetic antennas, after preliminary integration of the magnetic signals, all three components of the atmosphere are amplified and filtered in a wide and equal frequency band, according to the correlation between deeply bilaterally symmetrically limited electric and each of the magnetic signals determines the bearing to the atmospheric source, in addition I am an additional signal corresponding to the projection of the horizontal magnetic field on the direction of signal propagation, the distance to the lightning discharge is determined by the time interval between the arrival of the electric and additional magnetic signals. The resulting coordinates are displayed on the screen of the indicator of the location of the atmospheric source. The proposed method allows to increase the accuracy and reduce the time of measuring the location of lightning discharges.
