Abstract
A method for facilitating robust radar detection comprises generating a radar signal in a 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 ej·π/K·n, 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 generating a process input signal in the 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 e−j·π/K·n. In this context, K is defined such that a ratio Lc/2·K is a non-integer, and M is defined such that a ratio Lc·M/2·K is an integer.
