Abstract: A method for automatic multi-object localization and/or vital sign monitoring is provided. The method comprises the steps of receiving a radar signal in order to form a corresponding observation matrix, reducing noise by applying singular value decomposition to the observation matrix, processing the result of the singular value decomposition by an independent component analysis in order to estimate the corresponding sources, and estimating propagation channels of the estimated sources by minimizing the corresponding residual error based on the observation matrix and the estimated sources.
