Research On Proportion Guidance Method Of Missile

In missile guidance systems, the classical proportional navigation method is that people have been the most widely used method of a guide, but with the goal of increasing mobility; the classical proportional navigation method can not meet the requirements of the ballistic parameter on people. Therefore, based on the previous theoretical study, this paper studies on an extended proportional navigation method and to carries out the relevant theoretical analysis and simulation.This paper studies the classical proportional navigation method, through the analysis of the classical proportional navigation method which has the impact on the linear motion by the ballistic trajectory parameters, to simulate target, to draw the block, and simulation results show that it not suitable for high-performance goals. In this regard, according to the traditional dynamic differential equations of an extended proportional navigation method, using the extended proportional navigation guidance method to overload the normal curvature and the ballistic impact, and by changing the target maneuver, the target range after the perceived danger sinusoidal motion, random changes in speed of movement and the second line orbit, etc., to verify the advantages and disadvantages of extended proportional navigation guidance method, using MATLAB for the related programming and simulation.Simulation results show that the expansion ratio of projectile and target guidance law reduces the encounter time, close to the target missile in the normal overload when the volatility has improved its performance than the classical proportional navigation law. Randomness by changing the target, using the extended proportional navigation guidance method, having a good performance at the right targets random amount to finish normal overload.
