Acceleration-Compensated Zero-Effort-Miss Guidance Law

This paper shows that true proportional navigation guidance can be derived directly from a zero-effort-miss guidance law, and explains why the augmented proportional navigation guidance law does not take full advantage of the knowledge of target acceleration. A simple acceleration-compensated zero-effortmiss guidance law has been derived, which does take advantage of the knowledge of target acceleration. This paper also demonstrates that this new guidance law will outperform proportional navigation guidance and augmented proportional navigation guidance, even when the target acceleration is not perfectly known.
