Design Method of Guidance Handing-Over Bound Based on System with Stochastic Jump Structures

To decrease the missing distance,the handing-over bound between midcourse guidance and terminal guidance was studied when the system was disturbed by the stochastic noise.The system with stochastic jump structures can be modeled as two structures that are midcourse guidance mode and terminal guidance mode.Then,the probability of the system was analyzed based on the theory about the system with stochastic jump structures.Based on the optimal algorithm,the optimal handing-over bound that can make minimal expectation value and variance of the missing distance was obtained.The simulation of longitudinal pitch channel for one type of missile shows the effectiveness of the proposed approach.
