The role of the RFID polarization mismatch in the Simultaneous Localization and Mapping problem

Several localization algorithms exploit the dependence of phase shift backscattered RFID signal on tag to reader distance. However, in some configuration setups, also depends relative orientation between tag’s and reader’s antenna. In this paper we investigate effects Simultaneous Localization Mapping (SLAM) problem, by comparing approach where is included measurement model with it rather compensated through a time varying offset subject estimation. Simulation experimental results show that algorithm which includes provides better performances respect other approach. Some indications numerical are reported evaluate if may be beneficial solving SLAM problem.
