Changing rocket attitude to improve communication link performance in the presence of multiple rocket plumes

摘要

A method for commanding an attitude change of a boosting missile to tend to maintain good communication link quality includes the step of precalculating attenuation of a link between the boosting missile and a ground station in the presence and absence of multiple missile plumes. If the actual link attenuation is less than the precalculated attenuation in the absence of multiple missile plumes, no attitude change is commanded. If the actual link attenuation exceeds the precalculated value, the actual link attenuation is compared with the calculated attenuation in the presence of multiple missile plumes. If the calculated multiple plume RF attenuation is less than the actual link attenuation, the attenuation is deemed to be caused by some factor other than multiple plume attenuation, and produces a flag for commanding a change in attitude.
