FIELD: radio equipment.
SUBSTANCE: invention can be used for creation of multi-position radio systems for direction finding of objects in radio range of wavelengths at short range. Essence of invention consists in that method of determining spatial coordinates and speeds of objects scanning multi-position radio system involves placing in space several radio receivers, scanning a viewing area and mutually oriented by rotation arrays and basic vectors connecting receiver coordinate systems, forming, in one scanning period, vectors of vectors of directions to objects, distribution of said boxes as per belonging to specific objects, taking into account moments of time of formation of boxes and finding estimates of distances to objects and coordinates of velocity vectors by solving a system of equations of linear dependence of vectors, wherein an external radio transmitter is added, and scanning of antennae of receivers is carried out electronically in sequence of periods with time delay, wherein in each scanning period signals transmitted by the transmitter and received by the receivers are converted into complex spectra, selecting spectral components, amplitudes of which exceed threshold of useful signal detection and upon exceeding of threshold are determined by amplitude-phase method angular coordinates of azimuth and elevation of position of objects, after which, based on angular coordinates, vectors of direction vectors on objects in coordinate systems of receivers are found, groups are grouped according to membership of specific objects, then from coordinates of units of each group and differences of time moments of scanning make, by a certain rule, matrix A, calculating a matrix of weight coefficients W=(ATA)-1AT, where "T" and "-1" are symbols of transposition and matrix inversion, matrix W is multiplied from the left by vector B of coordinates of basic vectors and vector X=W·B of estimates of distances and coordinates of the velocity vector is obtained for each group of conjugated vectors, estimates of distances are multiplied by units and a vector of spatial coordinates of the object is obtained.
EFFECT: possibility of determining coordinates of direction vectors of objects by measuring angular coordinates of objects and finding spatial coordinates of objects together with estimates of vectors of movement thereof by increasing time between scanning periods in receivers when a transmitter is available.
