<p>PURPOSE: To calculate motional characteristics within narrow tolerance, by assigning a dependent phase difference and each position of an object to each displayed amplitude, and estimating an analytical compensation function, preferably a Tchebycheff function that is differentiable at least three times with scanning points obtained by arc-cosine-transforming signals displayed in a spot shape. CONSTITUTION: A title apparatus is used for measuring a motional characteristics of a bullet 2 moving in the barrel of a weapon. An estimation apparatus 7 includes an association unit 9 which associates each display amplitude value depending upon time in a measured signal with an attached phase difference and each bullet position. The association unit 9 associates a phase difference for each measured point and each bullet position. Otherwise, there is obtained an analytical compensation function, mainly a Tchebycheff function that is differentiable at least three times using scanning points already arc- cosine-transformed through the compensation unit 10, for example. There is ensured an analytical signal description or expression for the time dependent position of a bullet.</p> |
