METHOD FOR IDENTIFICATION OF BEARINGS OF RADIO SOURCES IN ANGLE-MEASURING TWO-POSITION PASSIVE RADAR SYSTEMS Russian patent published in 2005 - IPC

FIELD: radar systems, in particular, angle-measuring two-position passive radar systems.

SUBSTANCE: the problem of identification of bearings of radio sources in the claimed method is solved as follows: on the basis of the values of bearings of radio sources measured in each of two receiving positions and own co-ordinates of the receiving positions the altitudes of the radio source with respect to each receiving position are found, then the difference of these altitudes is found. On the basis of dispersions of the errors of determination of the bearings of the radio sources in each receiving position the value of the identification threshold is determined. By the results of comparison of the mentioned difference of altitudes with the identification threshold a decision is taken on belonging of the bearings, measured by different receiving positions, to one radio source.

EFFECT: expanded potentialities of passive radar observation, since it becomes possible to identify the bearings of several radio sources even if they are in the same plane.
