Abstract
A scanning mechanism for vehicle-mounted radar comprises a first noncircular gear attached to an input shaft, a second noncircular gear meshed with the first noncircular gear, and a connecting link having one end connected to an eccentric pin provided on the second noncircular gear and another end connected to an antenna transmission/reception section, thereby allowing the antenna transmission/reception section to effect swinging motion. Angular accuracy in a frontal direction is improved by delaying the scanning velocity in the frontal direction.
