Abstract
The invention relates to a method of estimating the time of arrival of a UWB pulse contained in an RF signal using a double quadrature receiver. The time of arrival is obtained from an estimate of the phase of the RF signal ((φRF(τ))) relative to the local oscillator signal in the first stage of the quadrature mix, and an estimate of the phase of the baseband signal ((φBB(τ)) relative to the first/second signal of the orthogonal base used in the second stage of the quadrature mix.
