METHOD FOR INTEGRATING INFORMATION WHEN DETERMINING THE DIRECTION OF AN UNMANNED AERIAL VEHICLE TO AN AIR OBJECT AND THE MAGNITUDE OF THE ALLEGED MISS Russian patent published in 2023 - IPC G01S13/52 G01S13/72 G05D1/02 G06F17/10 

FIELD: digital signal processing.

SUBSTANCE: invention can be used in on-board digital computers (OBDC) of manned aerial vehicles (MAV) and unmanned aerial vehicles (UAV) when they are homing to an air object (AO) according to information from several radar stations (RS), several UAV RSs and several tactical situation displays when aircraft and UAVs are used in combination. The method consists in jointly estimating the phase coordinates of the relative movement of the AO-Aircraft-UAV group and the tactical situation variant when combining information from several aircraft group RSs, several UAV radars and several tactical situation displays, based on transmission, over inter-aircraft navigation channels from the aircraft and channels radio corrections from the UAV to the command aircraft, of the phase coordinate measurements and indications of tactical situation displays formed in each RS of the aircraft group and each RS of the UAV, processing of complex measurements and complex indications of tactical situation displays in a multichannel filter operating in accordance with the procedure of quasi-optimal joint phase estimation of coordinates and state of the Markov structure of a linear stochastic dynamical system operating on the basis of a priori data in the form of a mathematical model (MM) of the system AO-Aircraft Group-UAV Group-Aircraft RS and UAV RS-Aircraft and UAV Displays with a random intermittent structure (RIS), including a set of linear models of the dynamics of the phase coordinates of the relative movement of each pair of AO - Aircraft (UAV), a set of linear models for measuring phase coordinates in the RS of each aircraft from the group, a set of linear models for measuring phase coordinates in the RS of each UAV from the group, a complex a Markov model for changing the tactical situation variant, a set of Markov models of indicators of the tactical situation variant of each aircraft from the group, a set of Markov models of indicators of the tactical situation variant of each UAV from the group, a model of uncontrolled random disturbances and interference, under initial conditions, the output generates filtered and smoothed estimates of the tactical situation variant, unconditional mathematical expectations of phase coordinates and covariation matrix of their estimation errors.

EFFECT: increased accuracy of recognizing a tactical situation variant and filtering the phase coordinates of the relative movement of the AO-Aircraft-UAV group in the integrated surveillance system Aircraft RS - UAV RS - Aircraft and UAV Displays.
