METHOD AND DEVICE TO DETECT COORDINATES OF RADIO-FREQUENCY EMISSION SOURCE Russian patent published in 2012 - IPC G01S13/46 G01S5/02 G01S3/14 

FIELD: radio engineering.

SUBSTANCE: inventions may be used to detect location of radio-frequency emission sources (RFES) from an airborne facility (AF) by a rho-theta method. Orientation of a direction-finder antenna array is taken into account relative to the AF board, as well as location and internal orientation of the AF in the space, and features of measurements area relief. In process of operation simultaneously with measurement of spatial parameters of RFES: azimuth θi and tilt angle βi; AF location in the space is assessed, as well as its orientation via angular parameters: list k_lpsi, pitch l_lpsi and declination ζ_lpsi., and also an underlying surface with application of a digital map of the measurement area. The specified result is achieved also by serial confirmation of a vector value of a direction at s RFES with a simultaneous transition from one system of coordinates to the other. The device to detect RFES coordinates, implementing the method, comprises a double-channel phase interferometer, eight calculators, five memory devices, a radio navigator, an angular orientation device of the AF, a control unit, a comparison unit, a switching unit, six inlet adjustment buses and an outlet bus, connected to each other in certain manner.

EFFECT: improved accuracy of RFES location detection.
