FIELD: radar ranging and radio navigation.
SUBSTANCE: invention relates to passive radio systems of millimeter wavelength range intended for observation of small-sized moving objects. For a radiometric system consisting of two mutually remote radiometers with space-scanning antennae, direction vectors of the objects are formed by the line of sight of the antennae and stored in angular coordinates of the azimuth and the elevation angle of the elements of the radio image matrices. During the movement of the objects of the unit, an unaccounted increment is obtained, which leads to coupling errors and determination of spatial coordinates of objects. Method enables to find conjugate pairs of vectors of direction vectors on objects in a system of two radiometers under conditions of moving objects and random interference by determining the rate of change of coordinates of unit vectors taking into account the moments of their formation.
EFFECT: possibility to increase probability of detection of all moving objects and accuracy of determination of their spatial coordinates.
