Abstract : IN LAUNCHING AN AIRBORNE MISSILE FROM UNDERWATER, BOTH THE LAUNCHING SUBMARINE AND THE MISSILE ITSELF RESPOND IN A RANDOM FASHION TO THE WAVES OF A CONFUSED SEA. The submarine motion contributes to the trajectory of the missile by imposing a set of random initial conditions on the missile. The resulting missile response, subject to both random forcing functions and random initial conditions, is then determined by employing the technique of generalized harmoonic analysis. The response resulting from the forcing function alone, called the direct respon e, has been determined previously; the response resulting from the initial conditions alone, called the indirect response, has also been determined. The particular feature of this report is the inclusion of responses resulting from the statistical cross-correlation between direct and indirect responses. It is shown, furthermore, that there is no cross-correlation between the initial conditions resulting from submarine roll and the other wave-induced causes of missile response. (Author)
