摘要： A signal proportional to steering angle is produced by a potentiometer controlled by the steering wheel, except for steering angles below about 0.1.degree. that are frequently used for corrections in driving on a straight course. For steering angles above about 0.5.degree., the signal remains constant in magnitude. The signal controls a range gate of the radar system suppressing the effect of echoes beyond a maximum range limit smaller than the intercept of a radar ray at the beam edge on an arc concentric with the curved path of the vehicle having a radius of curvature exceeding that of the vehicle path by a predetermined amount which is chosen so as to preclude reception of echoes from guard rails situated on the outside of highway curves. The steering angle signal can be provided together with other functions contributing to a maximum range limit operation for the radar for a more comprehensive elimination of echoes irrelevant to the anti-collision purpose of the radar, thereby reducing unnecessary warnings.
