/Electronic Device, Method For Controlling Electronic Device, And Program
Abstract

A method for controlling an electronic device. The method comprises transmitting a transmission wave from a transmission antenna unit including phase control units and a plurality of transmission antennas; receiving, at a reception antenna, a reflected wave that is the transmission wave having been reflected; and detecting a body movement of a subject that reflects the transmission wave, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave. The method further comprises, in response to detection of the body movement, controlling a beam of the transmission wave to track the body movement by calculating an inverse matrix of a covariance matrix of an input signal, and a weight of the beam of the transmission wave by using a value calculated by using a correlation value between a phase and an amplitude of each antenna.
