Research on Simulation of Laser Detecting System

Because of laser detection technique's superior performance,it has been widely used in target detection and identification system of AAA gun.Ranging is the most important content in Laser Detection System.But the target structure is complex,and simulation modeling is difficult.In order to improve the performance,in this paper,we took a certain type of fire control system of AAA gun as the study object,and proposed the scheme of the Laser Detecting Simulation System based on target equivalent circle model.On the basis of the current target route parameters and the target tracking error,and the relationships of the energy reflected by objectives,laser energy and the atmosphere were researched.And the model of its distance and the laser echo was built.Simulation results show that the model can qualitatively and quantitatively reflect the laser range finder performance in the actual environment,and can be used for the simulation of laser range finder in fire control system.
