Analysis And Simulation Of Integrated Guidance And Control System For R-77Missile

The composite guidance technology and the integrated guidance and controltechnology of air-air missile are the modern missile’s development trends, thecomposite guidance involving hand-off designed scheme of intermediateguidance, terminal guidance, and the integrated guidance and control technologyinvolving improvement of burst control algorithm which are most efficient pathsto enhance coordination of guidance and fighting, These technologies areachieved by computer, signal processing and mathematical tools and so on. Ourcountry is in the fundamental research and the experimental stages in these areas,analysising and researching foreign technology and principle, absorbing,improving and utilizing these technologies and principles，has the importantstrategic sense to our country’s theory development and manufacture ofcomposite guidance missile, shorten the gap with foreign countries.Firstly, the article uses R-77missile as an example, through analyzing complexguidance process of R-77missile, design a ballistic hand-off scheme; Secondly,analyzing missile-target Engagement process of R-77missile, the article usesthe advanced Kalman filter algorithm to filter it, utilizes filtered information todeduce and design the optimal burst angle and burst delay algorithm; Thirdly, thearticle establishes a simulation model of the integrated guidance and controlsystem of R-77missile, and then analyzes every submodule；Fourthly, briefdescribes the work principle of the timer of the missile fuze system, according tothe parameters of the timer of the R-77missile, uses FPGA to simulate it, usesreceived timing signals for simulating; Finally,analyzes and sets the initializedparameters of the system, build simulation platform, after simulating, uses theadvanced integrated guidance and control system to compare with the originalintegrated guidance and control system, referring to the parameters of the R-77missile,test and verify the rationality of the simulation platform of the integratedguidance and control system of the R-77missile and the optimal burst angle andburst delay algorithm tends to the ideal values, and verify the validity of burstcontrol algorithm.
