Component Description
Bendix ™ VORAD ® EVT-300 ™ System Components
The Bendix ™ VORAD ® EVT-300 ™ Collision Warning System is comprised of four
main components: the Antenna Assembly, Central Processing Unit, Driver Display
Unit, and the Interconnecting Harness. Two components, the side sensor and side
sensor display, are optional. Each of the components are shown in their approximate
location on a vehicle (see Figure 1 below), and their functions are described in the
following paragraphs.

Antenna Assembly
The Antenna Assembly located on the front of the vehicle, transmits and receives
low power, high frequency radar signals. The transmitted radar signals are refl ected
off objects in front of the vehicle and are received back at the Antenna Assembly.
The Antenna Assembly compares the difference between the transmitted and
received signals; converts this information into a digital format; and transmits it to
the Central Processing Unit (see page 6) for additional processing. The Antenna
Assembly is usually mounted in the center of the bumper. This mounting location
ensures that the radar beam is aimed directly in front of the vehicle. The Antenna
Assembly simultaneously monitors up to 20 objects within a 350 feet (106 m) range,
whether moving or stationary.
