Abstract
A radar system,is integrally accommodated in, for example, a door mounted exterior mirror case, wherein electromagnetic waves are emitted from a transmitting antenna,to an area of a right side and a backside of a driver's own vehicle; the electromagnetic waves reflected by objects are received by a receiving antenna,thus received waves are amplified by a receiving circuit,a Doppler frequency is measured; a situation of danger or safety is judged along with calculations of ranges and relative velocities from the objects in an operating circuit,a result of the judgement is displayed by LED,and a predetermined alarm and control is performed by a control circuit,equipped in a body of the own vehicle, based on information from the operating circuit,whereby detection of vehicles especially existing in an area being difficult for a driver to observe from a door mounted exterior mirror, for example that on a right back side of the own vehicle, are aided to detect.
