Abstract
In order to improve the performance of a pulsed laser radar, methods based on wavelet filter and pulses accumulation are investigated. The transmitted pulses and received return waves are modeled for the simulation of signal processing through a filter. It shows that the modeled return waves could be denoised effectively with the wavelet biro3.9 or db9 if it is on the basis of compulsory denoising. However, under the condition of high fidelity requirement for the waveform, the signal-to-noise ratio may not be increased considerably. Thus, a new filter which is based on the combination of pulses accumulation and a followed wavelet transformer is proposed and studied. The results show that it is preferab
