CLASSICAL VERSUS MODERN HOMING MISSILE GUIDANCE
F. Willim, Paul Zarchan · 1979
Modern guidance systems are generally accepted to yield better performance than classical proporticmal navigation systems. However, it is not always recognized that this better performance carries with it certain costs in inproved components or additional instruments. This paper compares a modern guiasnce system, MGS, to a classical proportional navigationai, PIV , homing misslle guidance system in terms of perforuance, robustness, and ease of implementation. Q aan titative first order miss distances are compared to show that MGS has the smallest miss if component tolerances can be met, but as component tolerances or measurement errors degrade, MGS degrades faster than PN until, at relatively large component or measurement erl-ors, PN has less miss distance than MGS.
