Terminal Air Defense Weapon System plays a key role in intercepting and defending important ground and accompanying air defense operations.Compared with the resources consumed by traditional field test weapon development,establishing a simulation platform for system verification can effectively reduce the cost of research and development.Therefore,based on the architecture of the terminal air defense weapon system and simulation technology as the core,this paper establishes a simulation platform that integrates requirement analysis,modeling design and system simulation verification of the terminal air defense weapon system,and provides relative data support and decision reference for the system solution demonstration of the terminal air defense weapon system.The main work of this paper is as follows:(1)Main Control System.The control center of the air defense weapon system is used to develop the data interaction protocol of the simulation platform as well as to control the advance of the simulation process,using the target track generation module in order to set the information of the true value of the incoming target data in the simulation,focusing on the simulation view generation of the air target posture,using3DSMAX software and Open GL library to establish the target view graphic sequence to simulate the camera detection of the tracking device and to adjust its display in the view according to the target’s actual size and motion attitude are used to adjust its display in the view.(2)Tracking system.Mainly designed and simulated the photoelectric tracking system,simulating the image data obtained under infrared and visible light detection of photoelectric tracking.The Canny edge tracking algorithm and the improved algorithm of background suppression of image source data combined with LCM and local entropy proposed in this paper are used to process the images and obtain the target position information.And an equivalent laser ranging model is constructed and the laser echo energy is calculated using the mass moment method.(3)Fire control system.The received target present point information is filtered,and the projectile flight time t_f is calculated from the target track,and the target future point information is obtained according to the shot table interpolation calculation.The influence of the change of projectile flight time t_f on the target firing elements is focused on the analysis.(4)Simulation platform experiments and data analysis.The process of the simulation platform is experimentally tested by setting the desired data,and the demand functions of the subsystems of the simulation system are tested and verified,and the simulation result data are analyzed.The simulation results show that the photoelectric tracking system of the simulation platform can meet the demanded tracking accuracy range and maintain stable tracking under the action of servo tracking system;the calculation of target-missing quantity of the fire control system is accurate and the error of shooting plurality solution is small.The simulation calculation and experiment verified the feasibility of the simulation platform of the terminal air defense weapon system.The research results of the simulation platform provide a means for the engineering demonstration,design and verification of the actual terminal air defense weapon system,and provide data support with certain reference value.
