TECHNIQUE OF AUTOMATIC TRACKING OF TARGETS UNDER SCANNING MODE Russian patent published in 2003 - IPC

FIELD: radiolocation. SUBSTANCE: proposed technique consists in measurement of phase coordinates of detected targets, in finding trajectories of targets, in extrapolation of phase coordinates of targets, in identification of measurement results with these or those extrapolated trajectories, in correction of evaluations of extrapolated coordinates by results of identified measurements, in arrangement of targets according to degree of their threat, in disposal of trajectories of tracked targets. In this case identification is carried out by minimal value of quadratic functional of quality calculated per each tracked trajectory, its minimal value is later used for adaptation of either vector of extrapolated phase coordinates or matrix of amplification coefficients of misclosures, or of both of them simultaneously. Extrapolation and correction of extrapolated values of phase coordinates by identification results of radar measurements are executed by algorithms of adaptive analog-discrete filtration. EFFECT: high authenticity of identified measurements, resolving power of radar, accuracy and stability of tracking of maneuvering targets, low probability of following false targets and confusion of trajectories. 16 dwg
