An Algorithm to Measure Motion Parameter of Swarm of Fragments with Six Light Screens
A apparatus made of six light screens can measure the flying velocity, paths of swarm of fragments. When a fragment pass through the six light screens, the time sequences, can be gathered in turn. One fragment generates a sequence of six times. The algorithm that distinguish the sequence from a group of sequences of time is put forward in this paper according to the coordinates of fragment position on a location identifier ae well as all the sequences of the fragments. The real velocity and accurate location of the fragment can be calculated with the algorithm designed. The sequences of time are arranged with every permutation that be supposed to be a real fragment time sequence. A real time sequence can be distinguished and recognized from all permutations by comparing the coordinates calculated with permutation with the real position on the location identifier as well as the restriction on the flying direction and passing times. The algorithm is proved accurate and effective by the simulation.
