The invention relates to measuring the signal delay t between a UWB transmitter and a FSCW receiver. According to the method, which is performed in a plurality of partial steps k, wherein k=1, 2, 3,..., a pulsed transmission signal Str is generated and transmitted by the transmitter, wherein the transmission signal Str comprises a broadband spectrum SPEKtr having a plurality of lines w, the transmitted signal Str is received by the receiver, wherein the received signal Srx comprises a broadband spectrum SPEKrx having a plurality of lines m, a frequency range B(k) having a narrower bandwidth HLPR and having a lesser number of lines m' is selected from the broadband spectrum SPEKrx of the received signal Srx, wherein a different narrower frequency range B(k) is selected in each partial step k, the channel impulse response hm' is determined using the selected frequency range B(k), and the delay t is determined from the channel impulse response in a fourth step.
