METHOD FOR DETERMINING CHARACTERISTICS OF FRAGMENTATION FIELD OF AMMUNITION, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC F42B35/00 

FIELD: weapons and ammunition.

SUBSTANCE: ammunition is blasted in a blasting chamber and time dependence of filtered Doppler frequencies of signals reflected from the part of fragmentation field relative to ammunition blasting moment is obtained. Radar speed meter is installed so that axis of antenna directivity pattern comprises acute angle α with the plane passing through longitudinal axis of ammunition and longitudinal axis of the slot of the blasting chamber. Doppler frequencies of signals reflected from the fragmentation field part are filtered when the field is located within the directivity pattern of the radar speed meter. Speeds of leading and closing fragments, average speed and depth of the fragmentation field are determined as per time dependence of filtered Doppler frequencies of signals reflected from the part of the fragmentation field relative to ammunition blasting moment. Then, number of fragmentation field echelons is determined. The device includes a blasting chamber, a semi-cylindrical target, ammunition, an initiation device and a radar speed meter.

EFFECT: improving test informativity.
