For solving the effective transformation of quick campaign, which is the biggest bottleneck, research on a new composite fuse which can meet the small bore antiaircraft weapon development. Through analyzing destroyed target mechanism of the modern small bore antiaircraft weapons, according to the method for improving target destroyed probability of the small bore antiaircraft weapon and based on the high g value micro-electro-mechanical systems (MEMS) sensor and passive static detection technology, introduce the application of MENS sensor and static detection technology in composite detonator, and describe its working mechanism and method. The result shows that the composite fuse can effectively improve the combat performance of small bore antiaircraft.
