Method, system, and computer program product for automatic multi-object localization and/or vital sign monitoring

A system for automatic multi-object localization and/or vital sign monitoring, the system comprising:

• a transmitting unit, and
• a receiving unit, and
• a processing unit,
• wherein the transmitting unit is configured to transmit a radar signal, the receiving unit is configured to receive a corresponding radar signal in order to form a corresponding observation matrix (X), and
• wherein the processing unit (12) is configured to reduce noise by applying singular value decomposition to the observation matrix (X), to process the result of the singular value decomposition by an independent component analysis in order to estimate the corresponding sources (Ŝ), and to estimate propagation channels (H) of the estimated sources (Ŝ) by minimizing the corresponding residual error (∥X−HŜ∥22) based on the observation matrix (X) and the estimated sources (Ŝ).
