Abstract
A method is provided for facilitating radar detection robust to IQ imbalance. The method comprises the step of generating a radar signal in digital domain comprising 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 integer variable. The method further comprises the step of generating a process input signal in digital domain from a reflection signal corresponding to the radar signal by multiplying the 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.
