A Review on Development of Fuse and Multimode Warhead For Short Range Tactical Missile

In the case of air defence missiles, impact is not usually achieved, and the missile is designed to explode at a given distance of the target, by using a fuze. A laser fuze produces laser pulses, the signals that are reflected off the target, and the warhead is activated to detonate, sending fragments off to damage critical parts of the target. The main difficulty, called fuze warhead coordination, is to choose the appropriate delay time to maximise the fragmentation damage. This can be done with fixed-delay laser fuzes, in which various delay components are chosen according to the engagement scenario and relative motion. Given the high-speed interactions, the process needs to be fast and efficient, thereby simple and robust delay systems are ideal for MANPADS. The fuze system (typically mounted near the warhead) consists of safety, arming and target-sensing components, and two types of fuzes are commonly used in missiles.
