Direct Statistical Analysis of Missile Guidance Systems via CADET (Covariance Analysis Describing Function Technique)

Abstract

The Covariance Analysis Describing Function Technique (CADET) -- a technique for the efficient direct statistical analysis of nonlinear systems with random inputs -- is extended in scope to permit 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 provided accurate missile performance projections with a small fraction of the computer time required for a comparably reliable monte carlo analysis.
