摘要
Guided projectile fired by the conventional artillery is one of the guided weapons which can strike the targets accurately by searching, guiding and controlling during the flight. Accurate spin rate measurement for guided projectile is the key to precise guidance and control. The spin rate measurement technology for guided projectile is summarized as follows. Firstly, the development situation of the guided projectile is discussed, then the necessity of measuring guided projectile spin rate is analyzed and measurement characteristics are explained. After that, spin rate measurement methods for spinning projectile are summarized. Meanwhile, spin rate measurement and information processing methods for guided projectile based on magnetoresistive sensor and high dynamic vibratory gyroscope are described. Finally, future research direction and focus of spin rate measurement technology for guided projectile are suggested.
