Millimeter-wave broadband positioning system for indoor applications

This paper presents the performance of a millimeter wave (MMW) positioning system operating in indoor environment and using broadband impulse signals. The main original contribution is an approach based on a focusing technique to minimize the performance degradations due to the multipath propagation. Experimental results validate the ability of the topology to perform multi-laterations based on a specific cooperation between sensors. The used focusing technique is detailed and its impact on the positioning accuracy is validated by numerous measurements.
