External Trajectory Measurement Data Processing Based on Wavelet Transform
Huang Yan · Journal of Projectiles.Rockets.Missiles and Guidance · 2011
In order to remove the noise of external trajectory measurement data,the principle of external trajectory measurement data was presented based on wavelet,and simulation was conducted by means of parameters of a new type of radar and cannonball,the simulation data was processed by the wavelet transform method and was compared with the result of Kalman filtering method.Simulation results indicate that the precision and practicability of wavelet transform method are better than Kalman filtering method when the trajectory model is unknown.
