Research On Missile Precision Guidance Based On Multi-sensor Information Fusion

As the world's major countries continue to increase investment in precision guided weapons,the precision guidance technology research and development of high reliability,high precision,strong penetration ability have become the future trend of weapon system.Based on multi-sensor information fusion technology,an improved information fusion framework is proposed in this paper.The scheme uses radar,laser and infrared three seeker to obtain autonomous guidance information,and uses the global optimal distributed fusion structure,and flexibly uses EKF,UKF,CDKF and other filtering algorithms to track the target.At the same time,in order to solve the sensor packet loss and delay,state fusion adds communication detection process,the high speed vehicle navigation has been more robust;In order to make the sensors to identify the target accurately,the precise guidance law of ballistic missile is designed based on the optimal control theory,The guidance law has a great improvement in comprehensive performance.Finally,the multi information fusion navigation system combined with precision guidance system,the joint targeting analysis software is written.The simulation results show that,the precision guidance technology of ballistic missile with multi-sensor information fusion has high guidance precision and anti-jamming ability.
