Detection Algorithm of Laser Radar Target Based on Wavelet Transform

Given the different transmission characteristics under the wavelet transform (WT) domain and the different distribution characteristics of frequency domain of the signal and noise, a novel approach for detecting laser radar target based on wavelet transform has been proposed. Usually, wavelet decomposition has been used to de-noise a digital signal corrupted by noise. In our approach, we applied the wavelet decomposition and modulus maximum detect the locations of laser radar echo signal. Simulations show that the proposed algorithms are more efficient than only utilizing wavelet decomposition in a big clutter background.
