Disclosed herein is a mover including an object detecting unit and either a masking processing unit or a transmission restricting unit as an additional processing unit. The object detecting unit detects an object based on a reception signal output from a receiver unit by having a transmitter unit transmit a scanning wave and by having the receiver unit receive a reflected wave, which is a component, reflected from the object, of the scanning wave. The masking processing unit performs masking processing of masking, in accordance with a timing at which, and/or a direction of incidence in which, a disturbance wave, not depending on the scanning wave, is incident on the receiver unit, a portion of the reception signal output from the receiver unit. The transmission restricting unit restricts a transmission range in which the transmitter unit transmits the scanning wave.
