Abstract

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.
