A method for localization and monitoring of living being targets in an environment comprise: transmitting (302) a sequence of radio frequency waveforms, the waveforms being a continuous-wave waveform modulated in frequency and/or phase； detecting (304) a sequence of reflected waveforms being reflected by a target and Doppler-shifted due to a movement of the target, forming (306) a sequence of waveform transforms, wherein the waveform transform comprises discretized information in a plurality of range bins, and wherein the information in a single range bin corresponds to reflections occurring at a specific sector in the environment； analyzing (308) information for a single specific sector in a sub-sequence of the sequence of waveform transforms, and determining (310) movement of a target in the specific sector based on the waveform transform information for that specific sector during a time period corresponding to the sub-sequence.
