METHOD AND DEVICE FOR DETERMINING THE MOMENT OF THE END OF THE ACTIVE SECTION OF THE BALLISTIC TRAJECTORY FROM SAMPLES OF RANGE SQUARES Russian patent published in 2021 - IPC G01S13/58 

FIELD: radar installations.

SUBSTANCE：invention relates to devices for trajectory processing of radar information. The technical result of the invention is a reduction in computational costs and the delay time for detecting the end of the active section of the trajectory (AST) of the flight of a ballistic object (BO). The specified result is achieved due to the fact that for the estimation of the second increment of the range square (SIRS), an α, β, γ filter is used, in which the omissions of the range measurements are taken into account with minimal computational costs, only the last range measurements or extrapolated values of the range squares when the measurements are omitted and the previous estimates of the first and second increments of the range squares are stored. The claimed device contains a series-connected distance squared calculator, α, β, γ SIRS estimation filter, a distance squared acceleration calculator, and a threshold device, the second input of which is connected to the output of the RMSD system calculator, and the output is the output of the claimed device.

EFFECT: technical result of the invention is a reduction in computational costs and the delay time for detecting the end of the active section of the trajectory (AST) of the flight of a ballistic object (BO).
