METHOD OF DEFINING CHARACTERISTICS OF AMMUNITION FRAGMENTATION FIELD AND DEVICE TO THIS END Russian patent published in 2012 - IPC F42B35/00 

FIELD: weapons and ammunition.

SUBSTANCE: ammunition is exploded in explosion chamber to obtain time dependence of filtered Doppler frequencies of signals reflected from portion of fragmentation field particles upon ammunition blasting moment. For this radar speed meter is arranged so that antenna pattern axis makes acute angle α with plane crossing ammunition lengthwise axis and explosion chamber lengthwise axis. Doppler signal frequencies are filtered for field located within limits of antenna pattern. Velocities of all particles are defined by time dependence of aforesaid signal upon ammunition blasting moment. Proposed device for testing ammunition 1 comprises semi cylinder target 2, explosion chamber 3, initiator 4 and radar velocity meter. Velocity meter comprises antenna 5, HF oscillator 6, broadband amplifier unit 7, n filters 8, and n switches 9. Second inputs of switches 9 are connected to output of initiator 4. Outputs of switches 9 are connected to PC inputs 10.

EFFECT: increased data content of tests.
