Description
technical field [0001] The invention belongs to the technical field of missile damage efficiency evaluation, in particular to a method for determining a detection area of a multi-branch fuze. Background technique [0002] Due to the limitations of application scenarios and battlefield conditions, the missile load is limited, and the requirements for accurate missile strikes are getting higher and higher. The damage effect of a single missile is one of the focuses of research. The study of projectile encounter is the key point to improve the damage efficiency of missiles. The accurate fuze detection area is given in the bullet-eye rendezvous experiment, which is very important for studying the multi-branch fuze bullet-eye rendezvous process, determining the target orientation, controlling the directional explosion point and improving the accuracy of damage calculation. [0003] At this stage, the real-object bullet-eye encounter experiment generally uses the physical objec...
