FIELD: physics. ^ SUBSTANCE: signals are received on reception points in different frequency ranges and in different sectors, where the number of sectors in different frequency ranges may not coincide, after which linear and analogue to digital converters are used generate a sequence of digital readings from continuous signals in different frequency ranges received from the reception points, based on which the set of signals received in one frequency range and in another sectors are combined into a radar image which is a two-dimensional matrix, where the number of columns corresponds to the number of readings, and the number of rows corresponds to the number times the input process is realised; characteristic irregularities caused by signals from unknown radio radiation sources are found on the obtained radar images, characteristic irregularities found on the given radar image are compared with others found on other radar images, based on coincidence of irregularity points obtained in different frequency ranges and from different reception positions, a composite radar image is created, which is a four-dimensional matrix in the "number of reading - number of realisation - frequency range - number of sector" space; coordinates of characteristic irregularities are calculated on the obtained composite radar image. ^ EFFECT: obtaining accurate and complete data on radio radiation sources in a complex signal-noise environment. ^ 2 cl |
