After translation,the skewness and kurtosis of a pulse waveform can be calculated combined with its new coordinate,which respectively reflect the symmetry and the Gaussianity of the waveform. In the pulse laser detection system,skewness and kurtosis can be used for the feature analysis of the echo signal. The change of the reflectivity and the fluctuate of the target surface will not lead to a large change of the skewness and kurtosis of the echo signal,while the saltation of the reflectivity and the fluctuate will cause a large skewness or kurtosis value,and the value of the two parameters are different under different saltation conditions. This provides an important basis for the feature analysis of the echo signal in pulse laser detection system.
