| Abstract: | The pulsed lidar system and continuous lidar system are improved by redesigning the parameters considering more details of the systems and choosing the more appropriate equipment according to limitations of the systems.After the simulation of the return signals,these two kinds of lidar systems are compared in SNR and difficulty of implementation.The results show that the pulsed lidar is more suitable for measuring the metastable Helium density of thermosphere and exosphere. |
