Research on Space-Based Missile Trajectory Characteristic Extraction Methods

摘要：

　　It is very hard to estimate missile trajectory based on space observation because of multi-error sources and complicated estimation methods.In this paper, we derive the relationship of wavelet coefficient and function derivative.Wavelet scales selection rule and characteristic extraction methods based on white noise are also introduced.Simulation results show that the ratio derived in this paper is correct and the rule of selecting wavelet scales is practical.It has great application worth on extracting characteristic of missile trajectory quickly and exactly by using wavelet transform.
