Abstract
A vehicle mounted obstacle detecting radar is disclosed. An electromagnetic wave radiated from the radar apparatus is received by a first antenna mounted on the ground and passed through a transmission line to a second antenna mounted on the ground and radiated thereby to a monitor area. A response electromagnetic wave from an obstacle within the monitor area is received by the second antenna and passed through the transmission line to the first antenna and received by the radar apparatus. When the transmission channel is arranged along a curved road, an obstacle in the curved road can be detected.
