【 摘 要 】

Aimed at the difficulty of extracting weak information such as projectile movement and precession during flight., this paper analyzes the characteristics of extracting the periodic motion information of the projectile from the original data, and designs the resampling and filtering methods based on the characteristics and measured data of a certain type of continuous wave radar system. This method achieves the purpose of non-destructive extraction of low frequency weak signals.
