There\'s been a growing interest now to theoretical and practical issues of different objects coordinate measuring. The interest is rea-soned by extraordinary wide and various applications of coordinate measuring (in navigation, location, control, astronomy and military sphere). One of the main areas of coordinate measuring is radio source positioning. The most widespread positioning systems are goni-ometrical ones that execute coordinate measuring with bearings intersection angle provided by radio direction finding stations. The article deals with a new approach to spatial radio source direction finding. A polarization method of spatial radio source direction finding is proposed on the basis of small-sized lumped antenna systems which are invariant to radio source polarization changes. The method proposed uses radio emission polarization as a coordinate informative parameter. The polarization method allows higher accuracy of radio source\'s azimuth θ and angle of elevation β measurement under prior uncer-tainty about polarization and spatial parameters of radio signals, noise and interference, when direction finding antenna system is limited in size.
