Multistatic Ultra-wideband Localization for NLOS Environments

Abstract

A procedure for the localization of a indoor target is proposed in this paper. In the through wall imaging or localization scenario, the imaging quality and the positioning precision is inevitably affected by the effects of wall, which must be taken into consideration and compensated. A multistatic radar system using the ultra-wideband pulses is used to estimate the location of a target inside a room. The wall effects are embedded in the proposed positioning algorithm, which gives better positioning precision than existing methods. Simulation results validate the validity of the theoretical analysis and positioning algorithm.
