Paper Abstract

Aiming at the low precision of small pulse laser ladar in practical application, the wavelet threshold de-noising algorithm is adopted to extract the echo signal. According to the echo signal equation and the ladar noise characteristics, a noisy echo model is established. In order to extract the echo signal, the wavelet threshold de-noising algorithm is used. Select the best wavelet basis and decomposition scale. According to the simulation results, the actual echo signal is processed, and the noise is effectively improved. The detection accuracy improves effectively.
