Abstract: In order to provide an object-sensing device and an object-sending method that are compact and low-cost by realizing an imaging function using fewer antennas than in common systems, an object-sensing device is configured from a transmitter that is provided with a transmission antenna and a receiver that is provided with a reception antenna. The transmitter irradiates an object with electrical waves at various frequencies, and the reception antenna receives an RF signal that is reflected off of the object. The receiver is provided with a phase shifter that individually controls the phase of the RF signal at each frequency, and an adder that adds the RF signals after phase control. The receiver is provided with functionality for detecting the position of the object on the basis of reflected waves from the object by having the phase shifter perform phase adjustment, in order to control the antenna gain of the receiver.
