Abstract
Signal processing is pivotal to laser radar system. Information like range, target's signature, etc. can be obtained from the processed laser signals. The received laser pulses for pulse laser radar are modeled. A wavelet filter is designed to denoise the contaminated laser signals. For the given laser signals, the filter based on the combination of correlation and thresholding is proposed. The gain of the filter is compared with the traditional thresholding method. It is shown that the combination of the correlation and thresholding denoising method is more effective for the weak laser radar signal processing compared with the traditional thresholding method.
