【Abstract】 CCD-based side scattering lidar is a new technology under study. It needs to process a lot of pictures,and the tradi-tional data processing method takes a long time. How to improve the computational efficiency is a difficult problem in data process-ing. The computational tasks in the data processing for side scattering lidar have been analyzed,and the key task which needs to beparallelized for the performance improvement has been summarized. Based on the OpenMP,two parallel algorithms are designed,and the validity of them is demonstrated by some examples. The results show that the two parallel algorithms are reasonable and feasi-ble,and the data processing efficiency of the side scattering lidar can be significantly improved by combination of them in differentperformance devices.更多还原
