Paper Abstract

Guanlan is a Marine science satellite designed by Qingdao Pilot National Laboratory for Marine Science and Technology. Its application goal is to detect atmospheric parameters and ocean parameters of water bodies. In order to verify the rationality of the design of the parameters of spaceborne lidar, we use MATLAB as the basic simulation software development platform. By reasonable design of laser pulse signal source, atmospheric transmission channel, underwater transmission channel, optical system and detector receiving model, link simulation and parameter inversion. To capture the information carried by the echo signal more accurately, we use 1ns as sampling interval, the energy of each laser pulse is converted to the number of photons and then hashed in each sampling interval according to the Gauss shape, achieving the process of launching, transmitting and receiving simulated signals. The simulation results show that the software platform achieves the purpose of evaluating and guiding the design process of system parameters.
