Contrastive Study Between Laser-beam-riding Guidance And Millimeter Wave Guidance Anti-tank Missile

With the advancement of new Main Battle Tank,new technology and new materials with faster and more firepower and more protection ability are developed,more and more countries make efforts to develop new anti-tank weapons with excellent performance.Key technologies of anti-tank missile system include the overall design technology,control and guidance technology,warhead design technology,propulsion technology and charge technology,etc.This paper takes the anti-tank missile as the research object,according to the target characteristics and guidance needs of tank,the laser-beam-riding guidance system and millimeter wave guidance system are designed respectively.First,the mathematical model of anti-tank missile is established according to the parameters of an anti-tank missile,and the aerodynamic simulation is carried out;According to the characteristics of rolling missile guidance and control loop,the mathematical model of rolling missile guidance and control loop is established,the model is simulated by using Matlab / Simulink.In this paper,the model following variable structure control design principle is used to design the stable loop of pitch and yaw in laser-beam-riding guidance system;Mature PID control algorithms is adopted to complete the system scheme design of seeker servo control system in millimeter wave guidance system,and establishes the linear mathematical model and simulation for each part of the control loop.The simulation results show that the two control systems designed have achieved good results,the laser-beam-riding guidance system has higher precision,while the millimeter wave guidance system has good anti-interference ability under the conditions of smoke and bad weather,etc.
