RFID-based passive localization algorithm

Recently,RFID tracking algorithm is mainly in active conditions,using the active tag in the experiments for static objects.The cost of present algorithm is large,and its complexity and long computing time determine its low adaptability in mobile condition.To solve the problem,on basis of TOA a lgorithm,passive tag reference is introduced,apassive location algorithm suitable for moving target is put forward.Basis simulation experiment results show,the proposed algorithm improves the operation time and the precision level,and has good practical applicability.
