Optimization of instrument orientations for ballistic-missle applications

This paper considers the analytic formulation of the problem of optimizing instrument orientations with respect to the probable circular error (CEP) criterion for ballistic applications. The main theme developed is the proper expression of acceleration-induced errors so that optimization techniques can be used without excessive computational requirements. With general and easily computed relations for CEP as a function of the instrument orientations, it is then proposed that a modified method of random search be used for optimization.
