Abstract
An apparatus (10) and method for selectively monitoring radar signals impinging on a vehicle is disclosed. The apparatus (10) comprises a speed determination circuit (20) that determines vehicle speed and provides a speed signal representative thereof to a comparator (22) that compares the speed signal to a preselected speed and provides an on signal when the vehicle speed exceeds the preselected speed and an off signal when the vehicle speed is at or below the preselected speed. When the comparator (22) provides the on signal, a radar detecting circuit (14) is powered to detect incoming radar signals and provide a radar detected signal to an alarm (18) that provides an alert in response to the radar detected signal. When the comparator (22) provides the off signal, the radar detecting circuit (14) is not powered and does not detect incoming radar signals.
