METHOD FOR DETERMINING CHARACTERISTICS OF SHELL COVERAGE FIELD, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2013 - IPC F42B35/00 G01P3/66 

FIELD: weapons and ammunition.

SUBSTANCE: invention provides for additional arrangement of two sensors at the specified distance between them; build-up of a structure of sensors in the form of three perpendicular lines of emitting diodes and photoreceivers; blasting of the shell on the motion trajectory and formation of a shell coverage field. Instants of time and number of subsequent actuations of elements of photoreceivers of additional sensors during movement of echelon groups of shell fragments to a target are recorded; time intervals between echelon groups of shell fragments are determined based on recording of sequences of sensors actuation moments. Then, a combination of actuated elements of photoreceivers is fixed in three planes; a coordinate of actuated elements of photoreceivers is determined based on information on the combination of actuated elements of photoreceivers. Then, a combination of actuated elements of photoreceivers is fixed in three planes; a coordinate of actuated elements of photoreceivers is determined based on information on the combination of actuated elements of photoreceivers. Besides, three coordinates of movement vectors of echelon groups of shell fragments and approach angles of echelon groups of shell fragments to the target are determined. Values of movement speeds of echelon groups of shell fragments, geometrical sizes of echelon groups of shell fragments in three planes and approach angles of echelon groups of shell fragments to the target are indicated.

EFFECT: improving informativity of ammunition tests.
