Squint biased PNG for intractable stationary target for passive seeker

摘要

For homing guidance with a passive seeker, when we have a tractable object near a stationary target in case that the target itself can not be tracked, we propose a new guidance law named Squint Biased PNG. With both the invariant geometric information and the output of seeker squinting at the additional object, it is shown to be possible to guide vehicle to the aimed target. Some interpretations are made to get the proper engaging geometry for realistic limitations. And some important error configurations are investigated to prove the guidance performance.
