Detection of Laser Radar Target Based on Wavelet Decomposition

A novel approach for detecting laser radar target based on wavelet decomposition has been proposed. Usually, wavelet analysis has been used to de-noise a digital signal corrupted by noise. In our approach, we applied the wavelet decomposition in a multi-resolution sense to only get the approximation of a signal and detect the target. Without reconstruction, it is easy to realize on real time. Experiments show that our approach leads to an effective method to detect the laser target in a clutter background
