With the development of guidance technology, intelligent fuzes and artificial intelligence, the warhead intellectualization enables the follow-up directional killing and blasting warhead to gradually become a hotspot field of the research of the modern air defense guided missile warhead. The follow-up directional warhead is arranged in a front cabin of the missile and can follow up with the seeker to aim at the target position in real time, the seeker is used for probing and giving information such as the position and the speed of a target to be struck, then the warhead follows the target to aim and detonate, and the high-speed fragments fly away towards the aimed target after explosion, so that the maximum utilization rate of the fragments is realized. Compared with the axial symmetrical layout of the fragments of the eccentric detonation directional warhead and the deformable directional warhead, the damage efficiency is greatly improved.
Although the utilization rate of fragments of the follow-up directional killing blasting warhead is greatly improved compared with the conventional fragment killing blasting warhead which uniformly scatters in the circumferential direction, the fragment scattering direction is not controllable, the concentration of the fragments in the target direction is not high, and the fragment density is not high.
