Bullet\'s dispersion characteristic parameters of intrusive cluster warhead directly affect the damage effectiveness of intrusive bullets against targets,and it\'s an important aspect of the cluster warhead\'s research.

This paper discusses the Monte Carlo method of calculating blockage probability of the intrusive submunition missile when attacking the airdrome runway, and takes one warhead for example to set up math model and imitation model.

The separation height of intrusive submunition missile directly affects the attacking effect of the missiles.

According to the problem that terminal angular of video-guided penetrating bomb was required to be controlled,the variable-structure guidance law with terminal angular constraint was derived,which included the influence of the gravity on the normal acceleration of trajectory.

According to the characteristics of passive homing penetrating bomb,the variable-structure guidance law with terminal angular constraint is designed.

In terms of phenomena of the experiments and measurements from the tests,based on the penetration equations,referred to Young s thought,a calculation method of "linear deceleration model" for a projectile impacting concrete targets is presented.
