Abstract
An object detector includes a wave transmitter to transmit a modulated wave in a predetermined frequency range to an object, a first wave receiver to receive sound waves and to generate a first wave reception signal indicative of the reception of the sound waves, a second wave receiver to receive sound waves and to generate a second wave reception signal indicative of the reception of the sound waves, an adder to generate a third wave reception signal by adding the first and second wave reception signals, and a controller to detect the object based on the third wave reception signal by causing the wave transmitter to transmit the modulated wave. The second wave receiver is farther from the wave transmitter than the first wave receiver. A fluctuation range of the third wave reception signal is not greater than a fluctuation range of the first wave reception signal.
