Abstract:	In order to optimize the trajectory scheme and explore the motion characteristics of a kind of transverse sensitive submunition, combined with the system composition and characteristics of the transverse sensitive submunition, this paper designs a trajectory scheme. Based on the classic Newton mechanics method and the first kind of Lagrange mechanics method, ballistic models of different stages are established respectively, and the theoretical equations are derived. The exterior ballistic characteristics and scanning parameters of the transverse sensitive submunition with or without disturbances are compared and analyzed. The results show that when there are disturbances, the scanning direction angle of the submunition system oscillates greatly in the deceleration guide section. After reaching the stable scanning section, the scanning direction angle remains stable, but has a certain angle with the horizontal plane. Compared with the ideal situation, the time for the disturbed submunition system to reach stability is prolonged, the steady falling speed slightly decreases, and the steady state scanning interval reduces. The designed trajectory scheme can effectively capture targets under the condition of actual disturbances.
