UWB M-sequence based radar technology for localization of first responders

Current solutions for localization of first responders are mainly based on fusion of multiple sensors and communication units. This solution usually requires too much space and weight that must be carried by rescue, police or military personnel. The goal of the paper is to demonstrate the benefits of UWB technology for such an application scenario. This technology represents a promising solution since it allows the design of a localization system where a tag that is carried by first responders can be small and light-weighted and despite of this it allows precise indoor localization and identification of the users. Moreover, UWB technology is inherently robust against narrowband jamming and eavesdropping. This paper describes a possible system concept which is based on M-sequence UWB technology. The ranging accuracy, the coverage and the number of users are evaluated by using UWB measurements as well as simulations.
