METHOD AND APPARATUS FOR DETERMINING LOCATION OF RADIO SOURCE Russian patent published in 2012 - IPC G01S3/14 

FIELD: physics.

SUBSTANCE: invention can be used to determine location of radio sources from a flight-hoisting apparatus (FHA) using a goniometric-ranging method. At the preparatory stage, a video camera is mounted under the fuselage. Orientation of the antenna system of the direction-finder and the video camera in three planes relative the FHA board is considered. During operation, simultaneously with measurement of spatial parameters: azimuth θ_ij and elevation angle β_ij at the j-th radio source, the location FHA in space and orientation thereof is estimated through angular parameters: roll k_ipsi, pitch i_lpsi and inclination ζ_ipsi. Measurement results of θ_ij and β_ij are successively refined while simultaneously switching from one coordinate system to another. The positive effect is achieved by guiding the video camera using the direction-finder onto the area with the j-th radio source by associating it with elements of the surrounding relief. The apparatus for determining coordinates of a radio source which realises the method has a two-channel phase interferometre, first, second, third, fourth, fifth and sixth computers, a radio navigator, a device for angular orientation of the FHA, a video camera with a controller and memory, connected to each other in a certain manner.

EFFECT: high accuracy of locating a radio source.
