A method for localization and monitoring of living being targets in an environment, the method comprising: transmitting a sequence of radio frequency waveforms in the environment from a transmitter (202; 402), each of said radio frequency waveforms being a continuous-wave waveform modulated in frequency and/or phase; detecting a sequence of reflected waveforms, wherein each reflected waveform comprises a contribution of the transmitted waveform being reflected by a target and Doppler-shifted due to a movement of the target, forming a sequence of waveform transforms, wherein each waveform transform is based on a single waveform in the sequence of reflected waveforms, and 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 in relation to the transmitter (202; 402) and further wherein said waveform transforms are Fourier transforms, and wherein a range bin corresponds to a single frequency range in the Fourier transform; analyzing information for a single specific sector in a sub-sequence of the sequence of waveform transforms, and determining 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, and wherein the method further comprises combining the sequence of Fourier transforms with speed information in the specific sector in the environment to obtain a combined measure of speed and magnitude of reflection from targets in the specific sector, wherein the combined measure of speed and magnitude comprises a multiplication of the speed with the magnitude. transmitting a sequence of radio frequency waveforms in the environment from a transmitter (202; 402), each of said radio frequency waveforms being a continuous-wave waveform modulated in frequency and/or phase; detecting a sequence of reflected waveforms, wherein each reflected waveform comprises a contribution of the transmitted waveform being reflected by a target and Doppler-shifted due to a movement of the target, forming a sequence of waveform transforms, wherein each waveform transform is based on a single waveform in the sequence of reflected waveforms, and 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 in relation to the transmitter (202; 402) and further wherein said waveform transforms are Fourier transforms, and wherein a range bin corresponds to a single frequency range in the Fourier transform; analyzing information for a single specific sector in a sub-sequence of the sequence of waveform transforms, and determining 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, and wherein the method further comprises combining the sequence of Fourier transforms with speed information in the specific sector in the environment to obtain a combined measure of speed and magnitude of reflection from targets in the specific sector, wherein the combined measure of speed and magnitude comprises a multiplication of the speed with the magnitude.
