Original Abstract Submitted

A sensor receives M reception signals including reflection signals reflected by a living body; extracts a living-body component transfer function matrix from first complex transfer functions and second complex transfer functions, the first complex transfer functions being obtained by recording an M×N complex transfer function matrix including complex transfer functions in time series, from M reception signals, the complex transfer functions each indicating characteristics of propagation between a corresponding one of transmission antenna elements and a corresponding one of reception antenna elements, the second complex transfer functions being obtained by estimating and recording M×N complex transfer functions in a second period, and outputting a position at which a spectrum function indicating a likelihood that a living body is present indicates a local maximum value, using a correlation matrix based on the living-body component complex transfer function matrix and a steering vector corresponding to each of measurement-target regions.
