2 Product Overview
2.1 Product Description
The products described here are part of a family of radars offered by Veoneer. They are intended for
automotive use, operating in the 76-77 GHz band.
The radars are fully integrated devices, with the RF part and DSP part on two different PCBs. The DSP
board controls the signal processing, as well as vehicle communications through CAN and diagnosis
functions. The RF PCB generates the FMCW waveform and transmit/receive the radio signal through
patch antennae.
The radars are integrated into a vehicle to enhance vehicle safety systems. They can be integrated as a
standalone sensor or sensors, or as part of more complex system that also may include cameras, lidar,
and other type of sensors to provide features like Automatic Cruise Control, Automatic Emergency Break,
Free space detections and other Autonomous Driving functions.
2.2 Product Application Examples
The product can be used, but is not limited to the following applications:
• Autonomous drive systems
• Automatic braking systems
• Lane change warning
• Adaptive cruise control
• Collision prevention systems
• Automatic lane change systems
• Pedestrian and Bicycle collision prevention
• Etc.

3 Typical Installation
The radar is typically installed in the positions of the vehicle depicted in Figure 1 often mounted behind a
bumper or emblem.
4 Hardware Description
The radar assembly consists of 2 PCB boards, one containing all the RF components, antenas and analog
to digital converters and the other containing all what is necessary for signal processing and
communications with the vehicle and power.
The boards are assembled in to a plastic housing that is laser welded toghether. The sensor has no
servisable parts and can’t be opened without permanent damage.

6 Sensor Features
The product can be used to support following applications among others:
• Blind Spot Monitoring (BSM) - The BSM algorithm detects and reports “Objects of Interest" on
either side of the vehicle, within a specified “blind spot” zone. The feature generates an output a
signal on the CAN Bus.
• Lane Change Warning/Assist (LCW/A) - The LCW/A algorithm detects and reports to the driver
that a highway licensable vehicle is rapidly approaching the host vehicle in one of the adjacent
lanes. The feature generates a signal which is used to drive a visual display placed in the outside
view mirror and/or request a chime or vibrating seat cushion, to alert the driver to the approach of
objects of interest within the defined LCA zone. The signal can also be used by the ADAS system
to engage/dis-engage lane change, as per described in UN R79.
• Rear Cross Traffic Alert/Break (RCTA/B) - The RCTA/B algorithm detects and reports “Objects of
Interest” behind the host vehicle, within a specified RCTA/B coverage zone when going backward. The
feature generates a signal which is used to drive a visual display to alert the driver of the presence of
objects of interest that may cause a collision with the host vehicle within the
defined RCTA zone. The signal can also be used to control the break.
