METHOD AND DEVICE FOR DETERMINING COORDINATES OF RADIO EMISSION SOURCE Russian patent published in 2005 - IPC

FIELD: radio communications.

SUBSTANCE: at preparatory stage method includes processes for determining amount of elementary snap zones, calculation for central and R peripheral bearing points with known coordinates of values of standard primary space-information parameters relatively to coordinates of position of centers of each elementary snap zone. At operation stage method includes processes of receipt of radio emission sources signals by group of R > 1 interconnected peripheral and central bearing points, measuring primary space-information parameters at outputs of antenna elements, while primary space-information parameters, measured by peripheral bearing points are sent to central bearing point, calculations for each elementary snap zone of difference between standard and measured primary space-information parameters, selection from produced values of minimal value, and coordinates of position of center of elementary snap zone are taken as coordinates of position of detected radio emission source. As primary space-information parameters values of differences of signals phases of all possible pairs of combinations of antenna elements within effect of each bearing point. Device at central bearing point additionally has adder, memory device, decision taking block and R + 1 analysis track.

EFFECT: higher precision.
