Abstract:
A method of determining hit parameters of a projectile passing in the vicinity of a target provided with a hit indicator comprising an indicator body suspended in a tow connection, by means of which the target is intended to be towed, the method comprising the steps of:detecting, at the hit indicator, shock waves generated by the projectile,determining a value of an angular position of the hit indicator body at instances when the shock waves are detected,making, based on results obtained in the step of detecting and on the value of the angular position, calculations for determining the hit parameters,wherein, in the step of determining a value of the angular position, the value of the angular position of the hit indicator body is determined by first measuring a body acceleration of the hit indicator body in a body measuring direction perpendicular to a plane through the indicator body and the tow connection and thereupon integrating the measured acceleration for finding a value of the angular position.
