The adjoint simulation method is an efficient, computerized method for the performance analysis of linear time varying LTV systems excited by deterministic andor stochastic inputs. It is based on the impulse response function or weighting function of the so-called adjoint system - an associated linear system derived from the original system by clever utilisation of the mathematical principle of duality. Once the adjoint system is obtained, the solution process using this method is quite straight forward regardless of the nature and number of inputs. In this report, we demonstrate the power of adjoint simulation in the context of guided missile homing loop studies and present a MATLAB tool that can be used for its speedy implementation and execution. The tool is demonstrated by using it to analyse the miss distance performance of a generic guided missile against an evading target.
