Abstract
Sinusoidal or weave maneuvers on the part of the target can make it pa rticularly difficult for a pursuing missile to hit. Normalized design curves are presented so that the guidance system designer can easily a ssess the influence of weave maneuvers on missile system performance. These curves show how the target weave frequency and amplitude along w ith the interceptor guidance system time constant and effective naviga tion ratio determine the size of the miss distance. Acceleration satur ation effects also are considered as a further important influence on system performance. Finally, suggestions are made showing how to impro ve system performance.
