Abstract
The invention relates to a phase detection method () comprising the following steps: receiving () a receiving sequence (Y) of values (Y, Y, . . . , Y) of a receiving signal (Y), said values (Y, Y, . . . , Y) having been sampled with a known sampling frequency fand said receiving signal (Y) representing a reaction to a transmitting signal having a known transmitting frequency f; providing () a sine sequence (S) and a cosine sequence (C) for each index (j) of the receiving sequence (Y), said sine sequence (S) comprising sine values of consecutive multiples of a known circular frequency, which depends on the transmitting frequency and the sampling frequency, and said cosine sequence (C) comprising cosine values of consecutive multiples of the known circular frequency; and determining () a phase real part (U) of the receiving signal (Y) based on a scalar product of the receiving sequence (Y) with the cosine sequence (C) and a phase imaginary part (V) of the receiving signal based on a scalar product of the receiving sequence (Y) with the sine sequence (S).
