Abstract
A FM radar alarm system for use on a motor vehicle detects a following motor vehicle in an adjacent lane behind the motor vehicle. The FM radar alarm system includes an FM radar module including a near-region monitoring antenna and a far-region monitoring antenna. The near-region monitoring antenna radiates a relatively wide radio-wave beam in a near region positioned behind the motor vehicle and extending over an adjacent lane. The far-region monitoring antenna radiates a relatively narrow radio-wave beam in a far region positioned behind the motor vehicle and extending over the adjacent lane.
