Abstract

An estimating device includes: a transmission antenna; a transmission signal generator that generates a multicarrier signal; a transmitter that outputs the multicarrier signal to the transmission antenna; a reception antenna; a receiver that measures reception signals including a reflected signal which is the transmitted multicarrier signal that has been reflected or dispersed by the moving body; a complex transfer function calculator that calculates, from the measured reception signals, a plurality of complex transfer functions indicating propagation characteristics between a transmission antenna element and a reception antenna element; a moving body correlation matrix calculator that calculates, for each of subcarriers, a moving body correlation matrix from the complex transfer functions; a subcarrier integrator that integrates the moving body correlation matrices; and an estimation processor that estimates the direction or position in which the moving body is present, using the integrated moving body correlation matrix obtained by the integration.
