- W2364307036 abstract "In this paper,the computer simulation technology is used,to research the laser echo signals change in different terrains and the actual measurement accuracy of laser altimeter are researched.Three-dimensional digital models in the terrains and mathematical models of the laser pulse and noise signal are established.The laser echo approximation algorithm for grid terrain data is innovated,which can avoid the division of the triangular facets,the test of facet blocks and blanking processing to simplify the calculation process.The simulated results of laser echo for the ideal planar targets are identical with the theoretical results.The simulation program is developed and run in the Matlab environment.It can simulate the spaceborne laser altimeter echo signals in a variety of conditions,and the results can be applied in quantitative analysis and study.Three typical terrain models of plane,stairs and Gaussian Wave types are designed in simulation experiments,and the actual measurement accuracy of spaceborne laser altimeter for the different areas are estimated." @default.
