METHOD AND DEVICE FOR DETERMINING COORDINATES OF RADIO-FREQUENCY RADIATION SOURCE Russian patent published in 2011 - IPC G01S13/46 

FIELD: radio engineering.

SUBSTANCE: inventions can be used for determining the location of radio-frequency radiation sources (RFRS) from the flying vehicle by using angle-distance finding method. At preparatory stage the orientation of antenna array of position finder is considered in three planes relative to the flying vehicle (FV) board. During operation together with measurement of spatial parametres: of azimuth θ_i and elevation angle β_i on radiation source there evaluated is location of FV in space and its orientation through angle parametres: roll k_lpsi, pitch l_lpsi and heading angle α_lpsi (deflection ζ_lpsi). Positive effect is achieved by successive refinement of measurement results of θ_i and β_i with simultaneous transition from one system of coordinates to the other one. Device for determining coordinates of radiation source, which implements the method, includes two-channel phase interferometre, the first, the second, the third and the fourth evaluators, memory unit, radio navigator, five input mounting buses, output bus and angular orientation device of FV, which are attached to each other in certain way.

EFFECT: improving accuracy of position measurement of radiation source.
