Abstract
A sensor includes at least one transmitting station including a transmission antenna; a plurality of receiving stations each including a reception array antenna; a first circuit that extracts, from signals observed by the reception array antenna of each of the plurality of receiving stations, living-body components, which are signal components transmitted from the transmission antenna and reflected by at least one living body; a second circuit that calculates, from the extracted living-body components, a plurality of position spectral functions, which are evaluation functions for evaluating a position of the at least one living body when viewed from the plurality of respective receiving stations; and a third circuit that integrates the plurality of calculated position spectral functions into one position spectral function, and calculates at least one maximum value of the position spectral function obtained as a result of integration to estimate the position of the at least one living body.
