Analysis on Analytic Arithmetic of Oriented Warhead's Contact of Missile and Target

Rather than general warhead, oriented warhead asks for more accurate explode-time and explode-angle. For this problem, this paper analyzes the error of traditional analytic model in approximate calculation. The analysis is carried separately within and without the distance between guide and warhead. In Matlab simulation, it is concluded that the distance will affect the explode-time deeply but will affect the explode-angle hardly.
