摘要：
A method of this disclosure comprises a step of generating (104) a radar signal in digital domain along at least one transmission path, the radar signal comprises a number of M periodic repetitions of a code sequence with a length Lc, multiplied with a progressive phase rotation
where Lc and M are integers, K is an integer or a non-integer, and n is a discrete time index corresponding to a code rate. The method further comprises a step of generating (105) a process input signal in digital domain along at least one receiving path from a digitized reflection signal corresponding to the radar signal by multiplying the digitized reflection signal with a progressive phase rotation
In this context, K is defined such that a ratio
is a non-integer, and M is defined such that a ratio
is an integer. Additionally or alternatively, K is defined such that a ratio
is a non-integer, and M is defined such that a ratio
is an integer, if the code sequence is a Zadoff code sequence.
