FIELD: weapons and ammunition.
SUBSTANCE: claimed invention comprises the registration of time intervals for determination of shell flight coordinates with the help of photoreceiver grid. Muzzle velocity is defined based on time interval measurement relative to two transducers arranged at the barrel bore and determination of coordinates of target hitting based on the registration of photoreceiver rule operated elements. Coordinated of the shell flight relative to the first and second contactless transducers are analyzed to define the dependence of shell scatter on shell velocity. Spacing between centres of the extreme shell-holes in Y and Z coordinates and radii of 50% and 100% of hits are defined to initiate the tests.
EFFECT: higher validity of data.
