具有终端约束的地面目标拦截比例导引

Ground Target Interception Proportional Navigation Law With Terminal Constraints

为实现地面移动目标的有效拦截,研究了一种具有终端约束的二阶段比例导引.对传统的比例导引进行了分析,在满足最小制导比例系数时,无法实现对于地面目标的全角度约束拦截;对二阶段比例导引进行了研究,该制导律主要分为导弹姿态调整制导和目标拦截制导2个阶段.采用实际二维导弹模型对结果进行了仿真,结果表明,该制导律可实现目标的有效拦截且具有较小的终端拦截角度误差.

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.
