A radar system includes an arithmetic processing unit, which calculates the second derivative of the intensity of a reflected wave and determines whether a target is an upper structure or a vehicle, based on the second derivative. Alternatively, the arithmetic processing unit decomposes the waveform of the intensity of the reflected wave into frequency components and determines whether the target is an upper structure or a vehicle, based on the intensity of a predetermined frequency component.

To enable a regenerated sound in the high-note range to sufficiently reach an ear of an operator (rider) during travel. A meter display unit is provided for displaying drive information such as a vehicle speed or a travel distance. Left and right speakers are disposed on both sides of the meter display unit for generating regenerated sounds such as English conversation and music. The left speaker includes a left midrange/woofer unit disposed on the left side of the meter display unit for regenerating midrange/low-note sound and a left tweeter unit disposed between the meter display unit and the left midrange/woofer unit for regenerating high-note sounds. The right speaker includes a right midrange/woofer unit disposed on the right side of the meter display unit for regenerating midrange/low-note sound and a right tweeter unit disposed between the meter display unit and the right midrange/woofer unit for regenerating high-note sounds.
