DEVICE FOR RECOGNIZING NONMANOEUVREING BALLISTIC TARGET BY FIXED SELECTION OF RANGE SQUARES Russian patent published in 2017 - IPC G01S13/58 

FIELD: radio engineering, communication.

SUBSTANCE: method is implemented by sharing the manoeuvre detector on the passive part of the ballistic trajectory (PUT) and the manoeuvre detector on the linear trajectory from the range squared samples. The decision to assign the escorted target to a class of non-destructive ballistic targets (BTs) is taken if the manoeuvre detector on the PUT has issued a message about the absence of manoeuvre, and the manoeuvre detector on the linear trajectory - about the presence of manoeuvre. The recognition device comprises a digital non-recursive filter consisting of a memory, two blocks of the squares of range multipliers by weight coefficients and two adders, and also contains two threshold devices, three coincidence circuits and a rms error calculator, connected in a certain way.

EFFECT: elimination of ambiguity of recognition of a non-destructive ballistic target.
