Abstract:
The current calibration methods of the projectile-velocity measurement system are introduced,and the problem and the unreasonableness of these methods are analyzed.Based on the principle of the mathematical statistics,the calibration method is investigated that measures the projectile-velocity at the same time by the multi-group zone-block device that is unbiased,uniform and efficient and uses the average of the measured value as the true value of the projectile-velocity at the point.The method advantages are analyzed too.The calibration system of the projectile-velocity measurement system based on the laser screen targets is established.The experiment and the data process prove that the method is not only feasible,but also provides an effective calibration method for quantificationally giving the uncertainty of measuring the projectile-velocity quantitatively.
