Signal Denoising of Laser Exploration System Using Adaptive Lifting Scheme;

According to echo signal characteristic of the laser exploration system,the paper adopts the adaptive lifting wavelet transform algorithm and brings forward a update filter and predictor filter design,which implements adjusted adaptively predict and update operator and strengthens the mutuality of the processing information and enhances the accuracy of systemic detective echo signal.

To pulse laser detecting system,when the optic path time difference with different scattering area elements is larger than the shooting laser pulse width,the back laser pulse width will be broaden,and the corresponding pulse peak power will be lower,adding to the limited receiving bandwidth,the target equivalent LCS can t be calculated using the general formula.
