BONDARENKO METHOD OF RADIO INFORMATION OBTAINING AND RADIO SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC G01S5/04 

FIELD: radio engineering.

SUBSTANCE: invention relates to electronic intelligence. Mentioned result is achieved due to that, when tracking aerial object based on primary radio information on four receiving stations difference-ranging information on aerial object radio path primary filtration is carried out, wherein aerial object movement is considered straight and uniform, otherwise - is taken as maneuver, making aerial object movement model, observation function derivative matrix and finding state vector and errors covariance matrix extrapolated value at receiving stations by signal from target arrival times difference primary fixation, supplied from one pair of information sensors by new aerial object, then, final information filtering is performed to obtain each aerial object refined trajectory parameters vector and receiving stations observation parameters algorithmic errors covariance matrix, output precise evaluation of each aerial object trajectory parameters for accurate monitoring of its flight nature and parameters, wherein at receiving stations filtration of difference-ranging information by aerial object and by time of its arrival is performed in certain manner.

EFFECT: rapid assessment of presence and nature of aerial object flight path.
