Abstract

Method for detecting an electromagnetic use-signal (2401) comprising: providing an use-signal; Providing an reference signal (2201) comprising M discrete tones with M ≥ 2; splitting the use-signal into N partial use-signals (2511) with N ≥ 2; splitting the reference signal into N partial reference signals (2521); mixing each partial use-signal (2511-n) with the corresponding partial reference signal (2521-n) to generate ∑ n = 1 N K n <img class="EMIRef" id="0d64a1ec-a3c5-4840-9d04-473fc17855e9-ia01" /> partial mixing signals (2531), wherein the nth mixing element (2530-n) generates Kn partial mixing signals (2531-n); digitizing the partial mixing signals (2531) that ∑ n = 1 N K n <img class="EMIRef" id="0d64a1ec-a3c5-4840-9d04-473fc17855e9-ia02" /> digitized partial mixing signals (2541) are generated; reconstructing the use-signal (2551) using a transformation that relates partial mixing signals to the use-signal and that comprises at least one model parameter related to a measurement property, characterized in that: at least one partial reference signal comprises at least two spectral tones, and the ∑ n = 1 N K n <img class="EMIRef" id="0d64a1ec-a3c5-4840-9d04-473fc17855e9-ia03" /> of the partial mixing signals comprises redundant information to determine the parameter.
