Abstract

1. Дальномерный способ определения координат местоположения источника радиоизлучения по данным измерений в не менее трех взаимно удаленных друг от друга пунктах приема радиосигналов, заключающийся в том, что в пунктах приема производят определение расстояний от источника радиоизлучения до каждого из пунктов приема и по полученным расстояниям вычисляют координаты местоположения источника радиоизлучения, отличающийся тем, что, с целью обеспечения определения координат местоположения источника радиоизлучения в пассивном режиме в условиях отсутствия взаимной временной синхронизации пунктов приема, в пунктах приема определяют интенсивность источника сигнала, а затем по величине интенсивностей сигналов вычисляют расстояние от источника радиоизлучения до каждого из пунктов приема по величине затухания сигнала на трассе распространения от источника радиоизлучения до точки приема.2. Устройство определения декартовых координат источника радиоизлучения, содержащее три пространственно разнесенных ненаправленных антенны типа полуволновый вибратор; три радиоприемника; три аналого-цифровых преобразователя и вычислитель координат источника радиоизлучения, при этом выход каждой ненаправленной антенны подключен ко входу соответствующего радиоприемника, а выход каждого радиоприемника подключен ко входу соответствующего ему аналого-цифрового преобразователя, причем антенны с радиоприемниками и аналого-цифровыми преобразователями расположены в пространстве таким образом, что образуют вершины равностороннего треугольника со стороной равной базе размещения, отличающееся тем, что, с целью обеспечения 1. The range-finding method for determining the coordinates of the location of the source of radio emission from measurement data at at least three points of reception of radio signals mutually remote from each other, namely, that at the points of reception, the distances from the source of the radio emission to each of the points of reception are determined and the coordinates are calculated from the obtained distances the location of the source of the radio emission, characterized in that, in order to ensure the determination of the coordinates of the location of the source of the radio emission in the passive mode under In the absence of mutual time synchronization of the receiving points, the signal source intensity is determined at the receiving points, and then the distance from the radio emission source to each of the receiving points is calculated by the signal intensity value from the signal attenuation along the propagation path from the radio source to the receiving point. 2.
