PROBLEM TO BE SOLVED: To provide a radar device with its processing efficiency increased by stopping the analysis of signals received by one sensor in a domain where two detection domains overlap. SOLUTION: The radar device includes: a radar sensor 21 for long distance comprising a first transmission part for transmitting an electric wave to a first detection area, a first reception part for receiving a reflected wave of the electric wave from the first detection area, and a first signal processing part 23 for detecting an object existing in the first detection area; a radar sensor 22 for short distance comprising a second transmission part for transmitting an electric wave to a second detection area larger in width and shorter in distance than the first detection area, a second reception part for receiving a reflected wave of the electric wave from the second detection area, and a second signal processing part 24 for detecting an object existing in the second detection area; and a processing part 25 for unifying information supplied from the first and second signal processing parts. The second transmission part is characterized by stopping the transmission of an electric wave to an area where the two detection areas overlap. COPYRIGHT: (C)2008,JPO&INPIT |
