METHOD OF TARGET IDENTIFICATION AND DEVICE TO THIS END Russian patent published in 2013 - IPC F41G7/26 G01S7/495 G01S7/51 

FIELD: weapons and ammunition.

SUBSTANCE: air target is detected, angular speed of optoelectronic module guidance rate is selected by aligning cross at display with target, said module is switched into automatic tracking mode, actual range to target is computed to convert range digital code into video signal to be displayed as digital inscription. Additionally defined the following parameters: target motion angular speed by measuring time intervals of target displacement relative to preset angular points, target angular acceleration by estimating dynamics of angular speed variations, dynamics of target acceleration variation by subtracting the last and previous angular accelerations, target tracking is defined. In case dynamics of target angular acceleration variation is smaller than preset value, tracking of IR trap is defined. In case dynamics of target angular acceleration variation is greater than preset value, portable complex operator is notified about IF trap lock-in.

EFFECT: higher noise immunity.
