Laser radar range profile analysis and simulation

In this paper, laser radar range profile theory and simulation method are investigated. Laser radar range profile theoretical formula is given based on the theory of Gaussian laser beam, BRDF, and target shape. On the purpose of simulating the range profile of certain targets, the geometrical 3D models of some simple and complex objects are constructed respectively, and then the viewpoint coordinate and target coordinate are established. The location information of vertexes and facets can be obtained and exported to utilize. In next step their laser radar range profiles in many postures are acquired and compared sequentially. The influences of Gaussian pulse width, target shape, size and transmit-receive angles on the simulation results are discussed. In this way this paper can provide theoretical and simulation methods and bases for extracting target features and recognizing targets using laser radar range profiles.
