Abstract
A radar device has a long range radar sensor having a first transmission and receiving section for transmitting and receiving radio wave to a first detection range and a first signal processing section for detecting an object existing in the first detection range; a short range radar sensor having a second transmission and receiving section for transmitting and receiving a radio wave to a second detection range of which width is wider and of which distance is shorter than the first detection range and a second signal processing section for detecting an object existing in the second detection range; and a processing section for integrating information supplied from the first and second signal processing sections. And one of the long range radar sensor and the short range radar sensor stops a detection operation of the object to an overlapped range of both the detection ranges.
