Ground Target Interception Proportional Navigation Law With Terminal Constraints

Hua Wenhua

Abstract

To realize the effective interception of ground motional target,two-stage proportional navigation(PN) with terminal constraints was researched.The classical PN was analyzed,which can not realize the whole angles constraints interception of the target under the minimum guidance proportional coefficient.Two-stage PN was analyzed.This guidance law is composed of missile attitude adjustment stage and target interception stage.The realistic 2D missile model was adopted for the simulation.The results show that this guidance law can realize the effective interception,and it has small terminal impact angle error.
