METHOD OF ADAPTIVE MAINTENANCE OF RADAR OBJECTIVES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC G01S13/66 

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. This result is achieved due to the fact that the device additionally introduces a delay device per clock and two coordinate transducers, which provide the implementation of the method of adaptive tracking of radar targets, based on converting the target coordinates obtained from the radar to rectangular coordinates, which are used to estimate the trajectory parameters of the Kalman filter target, and the tracking is carried out in the velocity-related coordinate system associated with the target, state vector of which includes the coordinates of the target x, y, z, the velocity – V, the course – K, and the inclination angle of the trajectory – ϕ, and upon receipt of a previous estimate of the velocity of the target V_(i-1), of the course K_i-1 and the trajectory angle φ_i-1 in the associated high-speed coordinate system, correctives are calculated for the filter parameters – Δν_i, ΔK_i, Δφ_i – necessary to adapt the parameters a_x, a_y, a_z at each step of tracking the target, which are used to take into account the direction of movement of the targets and the various possibilities connected with this direction for carrying out maneuvers in different Cartesian coordinates when receiving the next estimate of the trajectory parameters of the accompanied target.

EFFECT: technical result is an increase in the sustainability of the tracking and accuracy of the estimation of the parameters of the trajectory of the accompanied target under conditions of uncertainty in the dynamics of its movement.
