Abstract

A sensor includes circuitry and a memory, wherein the circuitry acquires an N×M first matrix having complex-number transfer function components representing propagation characteristics between a transmit antenna element and a receive antenna element, from N receive signals received by each of M receive antenna elements for a predetermined period. The circuitry extracts a second matrix, corresponding to a predetermined frequency range from the first matrix, representing components influenced by a vital sign, and estimates a position of the organism with respect to the sensor by using the second matrix. The circuitry also calculates a first distance, indicating a distance between the organism and the transmit antenna, and a second distance, indicating a distance between the organism and the receive antenna. The circuitry further calculates a radar cross-section value with respect to the organism, and estimates a posture of the organism.
