| Abstract: | A new measurement method for nutation cycle has been put forward with the measuring theory of non contact vertical target. After instantaneous position arranged by time sequence is measured where missile or cannonball passing through the light target, the nutation angle can be calculated. According as nutation angle of variant position, the nutation period can be obtained. The constituion and function of measurement system for measuring the nutation angle have been put forward. |
