METHOD OF CLUSTERED AIR TARGET TRACKING

摘要

FIELD: radiolocation.;SUBSTANCE: method implies parallel tracking based on the procedure of optimum multidimensional linear discrete Kalman filtration in each optimum filter from a matrix of Doppler frequency resolvable elements of clustered air targets, determination of their quantity using the Pearson chi-square criterion, and recognition of the flight dynamics variant in different battle array forms, by the minimum actual filtration error generalised variance criterion. The state vector evaluation is generated at the output only after a decision on the validity of a composite hypothesis concerning the quantity of Doppler frequency resolvable elements of clustered air targets and their flight dynamics variant is made.;EFFECT: expansion of clustered air target element state recognition functionality during Doppler frequency tracking of targets.;1 dwg
