| Abstract: | Aiming at the limitation of testing methods for projectile rotating speed, a new testing method of projectile rotating speed is put forward. The radar echo micro-Doppler modulated mathematic model caused by projectile rotation is built by using micro-Doppler effect resulted from CW radar detection of projectile rotations, the internal relationship between micro-Doppler frequency and projectile rotating speed is derived, and testing methods of micro-Doppler data for projectile rotating speed is provided. The projectile rotating speed is extracted by micro-motion identification and digital demodulation of projectile rotation, and the good testing effect is validated by shooting range test. |
