Description
technical field [0001] The invention relates to the technical field of guided munitions measurement, in particular to a device for measuring the initial velocity and rotational speed of guided munitions and a measurement method thereof. Background technique [0002] Accurately measuring the initial velocity and rotational speed of guided munitions in flight is of great significance to the identification of the aerodynamic parameters of the munitions, the study of the outer ballistic characteristics, and the design of the guidance system. The muzzle velocity of the barrel-launched ammunition is usually 800-1000 m / s, and the rotation speed is usually 30-100 r / s. The current method of measuring the muzzle velocity and rotation speed through high-speed cameras or Doppler radar has low accuracy, or can only measure the average It is impossible to dynamically and accurately measure the initial velocity and rotational speed of the guided munition in real time.
