Abstract:
In accordance with the present invention, an adaptive cruise control system includes a radio frequency (RF) transmit receive (TR) sensor module (or more simply "sensor") disposed such that a detection zone is deployed in front of a vehicle. The sensor includes a sensor antenna system which comprises a transmit antenna for emitting or transmitting an RF signal and a receive antenna for receiving portions of the transmitted RF signal which are intercepted by one or more objects within a field of view of the transmit antenna and reflected back toward the receive antenna.
