Implementing Backprojection at Base Station for Precise Localization in Indoor Environment

Mobile equipment with an integrated radar system allows active localization by realizing monostatic, bistatic, multistatic and passive SAR. For mobile user localization, it is also possible by implementing backprojection at base station. In the paper, an approach for precise mobile user localization by implementing backprojection at base station is proposed. The simulation shows the feasibility of the proposal. Some technical issues such as accuracy and backprojection ambiguity, are also addressed. The practicality of the proposal is also demonstrated with a practical frequency-modulated continuous wave (FMCW) radar system and a monostatic radar measurement based on the system.
