Abstract:

The Covariance Analysis DEscribing Function Technique CADET -- a technique conceived at TASC for the efficient direct statistical analysis of nonlinear systems with random inputs -- is applied to the study of a complicated, highly nonlinear model for a tactical missile homing guidance system. Numerous parameter sensitivity studies are performed, with selected cases verified by the monte carlo method. The validity of the assumptions underlying the CADET theory is investigated and the impact of possible errors in these assumptions on the accuracy of CADET is assessed. In every realistic situation studied, CADET provides accurate missile performance projections with a small fraction of the computer time required for a comparably reliable monte carlo analysis.
