Claim Text:
1. A device for determining an arrival time of a received ultra-wide band (UWB) signal comprising at least one pulse modulated at a carrier frequency, said device comprising: at least one translation stage for translating to an intermediate frequency, the at least one translation stage comprising a quadrature mixer comprising I and Q mixing channels; at least one integration stage connected to the at least one translation stage, for integrating signals delivered on the I and Q channels on a time window and providing integration results for each of the I and Q channels respectively; and means for controlling said at least one translation and integration stage for: calculating means for calculating a first phase value Θ  a second phase value Θ  and deducing therefrom a phase deviation ΔΘ=Θ
