Study on simulation technique of laser detector

A simulation method is introduced to test a laser detector. Firstly, the target and background characteristics are analysed, aimed at a certain laser proximity detector, and the simulation algorithm of the detected target and background characteristics is presented. Then we accomplish the mathematical modeling, 3D visualization modeling and the target engagement modeling of the simulation. The simulation interface and program flow chart are designed tentatively. A graphics software platform for the simulation, based on OpenGL, is created under the Visual C++ 6.0 development workspace to realize the visualization simulation and show the relationship between engagement status and output data. The modeling and simulation algorithm mentioned is proved to be feasible by a simulation experiment and to be an effective method to estimate the performance of the laser detector.
