A receiving device operates for receiving an echo wave caused by reflection of the forward electromagnetic wave at an object, and converting the received echo wave into a first received signal. A scattered-wave detecting device operates for detecting a scattered wave reaching the receiving device and caused by reflection of the forward electromagnetic wave at an obstacle which occurs prior to the reflection of the forward electromagnetic wave at the object. A cancel-signal generating device operates for generating a cancel signal to cancel a scattered-wave-corresponding component of the first received signal generated by the receiving device in response to the scattered wave detected by the scattered-wave detecting device. A scattered-wave canceling device operates for removing the scattered-wave-corresponding component from the first received signal in response to the cancel signal generated by the cancel-signal generating device to change the first received signal to a second received signal. A distance calculating device responsive to the second received signal operates for measuring a time interval between a moment of the transmission of the forward electromagnetic wave by the transmitting device and a moment of the reception of the echo wave by the receiving device, and calculating a distance to the object on the basis of the measured time interval.
