In process of striker movement by measuring unit dependence of linear acceleration A MUi  is registered on time   on time scale of measuring unit. Using ground equipment, speed values are determined ν 0  and time   at the moment of collision of striker with obstacle on time scale of ground equipment. After the striker stops in the obstacle, the value of the final penetration depth of the striker x f  into the obstacle is measured. According to the measured dependence of linear acceleration   on time   on the time scale of the measuring unit, the moment of impact of the striker with the obstacle   is determined.
