METHOD FOR RELATIVE BEARING MATCHING OF RADIO EMISSION SOURCES BY THEIR RADIO ENGINEERING CHARACTERISTICS USING TWO-POSITION PASSIVE RADIOELECTRONIC MEANS Russian patent published in 2018 - IPC G01S3/72 

FIELD: radio engineering, communication.

SUBSTANCE: for the received signal from the radio emission sources (RES) a target record form is generated to fill in the information about the radio engineering parameter value and relative bearing, where the object is detected. After that, joint processing of the target record forms, received at different positions by passive radioelectronic means, is carried out. The matching of RES relative bearings is carried out by comparing the record forms received from two spaced radioelectronic means, according to their radio engineering characteristics. For this purpose, two samples of one radio engineering parameters, obtained during the review of the object by the first and second passive stations, are used. The matching is carried out on the basis of Student's t-criterion, which allows one to check the equality of the mean values in two samples. As a result, it is established that one radio emission source belongs to two observing stations, or it is stated that two different stations are observed. The procedure is repeated for all pairs of detected RESs by the first and second radioelectronic means.

EFFECT: determination of the coordinates of radio emission sources.
