METHOD FOR ADAPTIVE TRACKING OF TARGETS WITH FORMATION OF A GATE IN A COORDINATE SYSTEM ASSOCIATED WITH THE TARGET Russian patent published in 2019 - IPC G01S13/58 

FIELD: radar ranging.

SUBSTANCE: invention relates to the field of radar, in particular to the secondary processing of radar information, and is intended for use in tracking systems for mobile purposes. Technical result is achieved due to the fact that the strobe is formed in a coordinate system in the form of a truncated elliptic ball sector limited by heading, trajectory inclination angle and range with values K_min, K_max, φ_min, φ_max and D_min, D_max respectively, the values K_min, K_max is calculated based on course and mean-square deviation (MSD) course estimates taking into account calculated rate of course change, values φ_min, φ_max is calculated based on estimates of path inclination angle and MSD of trajectory inclination angle based on calculated rate of trajectory inclination angle variation, a D_min, D_max – based on speed and MSD speed estimates with allowance for calculated linear acceleration, and deviations , calculated at current i-th reference to target, are used to adapt the shape and sizes of tracking gate to intensity of maneuvering of tracked target at each tracking stage.

EFFECT: high reliability of radar information.
