a transmitter configured to transmit a transmission wave;
a receiver configured to receive a reception wave, which is the transmission wave reflected by and returned from an object, until a predetermined measurement time elapses after the transmission wave is transmitted;
a detector configured to detect the object based on distance information based on the reception wave received by the receiver; and
a reception controller configured to set a measurement time after a detection of the object to be shorter than a measurement time after a non-detection of the object.
