| Abstract: | The commonly used pulse laser ranging algorithm has the shortcomings that the ranging speed and accuracy are not high enough,and it is only suitable in the case that the ranging finder and the target are relatively static or slowly moving.In order to solve the problems,a new pulse laser ranging algorithm employing mexh wavelet transform was put forward.Not only this algorithm can accurately measure the time difference between emission pulse and echo pulse,but also it can effectively reduce the noise interfe... |
