Differential Game Guidance Law Against High Maneuver Target with Different Information Patterns

摘要

A new differential game guidance law using only partial information about the target orientation for homing missile to intercept high maneuver target is proposed. First, the guidance model is formed based on missile-target line of sight (LOS) angular rate, the performance index focus on minimum of final LOS angular rate, and then the problem is solved by minimum principle. In the aspect of information predominance, this new guidance law is more robust than previous differential game guidance law of perfect target maneuver information or delayed target maneuver information; via a computer simulation it is show a significant decrease in the miss distance comparing with two other guidance laws.
