So, the paper presents the time scale amplifying method to enhance the accuracy of the pulse laser ranging.

而高精度脉冲激光测距系统往往难以达到低成本和便携的要求。

The result shows that, compared with the time-wavelet power spectrum, the scale-wavelet power spectrum has a higher recognition accuracy and smaller dimension of feature vector.

结果表明，尺度-小波能量谱和时间-小波能量谱相比有较好的分类效果和较低的特征维数。

The examples show that the approach can greatly reduce the calculating scale and time with satisfactory accuracy.

本方法大大地减少了自由度，缩短了计算时间。算例表明，计算结果令人满意。
