Abstract:
1. A radar system for a vehicle, which is for determining a height of a target, comprising: an oscillator that is configured to oscillate to generate a transmitted wave; a transmitting antenna that is configured to output the transmitted wave; a receiving antenna that is configured to receive a reflected wave from a target; an angle detector that is configured to reduce noise of the reflected wave based on an angle of incidence of the reflected wave on the receiving antenna; and an arithmetic processing unit that is configured to calculate an intensity of the reflected wave, in which the noise has been reduced, and to determine a relative distance to the target, wherein the arithmetic processing unit is configured to take a second derivative of each intensity associated with the relative distance, and to determine the height of the target in accordance with a number of the second derivatives of the intensities that are greater than a predetermined threshold value.
