The invention relates to a method of detecting at least one human-like and/or animal-like target in a detection zone by using a radar-based detection system comprising at least one FMCW radar, the method comprising:-generating radar signal and acquiring reflected radar signal at time ti,-applying signal processing on acquired reflected radar signal in order to improve SNR,-analysing the signal spectrum in order to detect distinguish features of target,-classifying distinguishing features of target in order to determine if target is relevant for further actions,-determining if a target deemed relevant for further actions is a false alarm,-applying further actions if target deemed relevant for further actions is not a false alarm. The invention further relates to a radar-based detection system for detection of targets using said method.
