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 24.050 - 24.250GHz band.
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:
•Blind Spot Detection
•Rear Cross Traffic
•Lane change warning
•Rear collision prevention systems
•Automatic lane change systems
•Pedestrian and Bicycle collision prevention

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.
Figure 1: Typical Installation Positions
4 Hardware Description
The NB RADAR is a fully integrated 24GHz radar sensor with both RF and DSP modules on the same
PCB. The design supports a combination of pulsed Doppler and chirped FM waveforms that can detect
moving or stationary vehicles in a high clutter environment.
The sensor’s DSP – a multicore processor - controls all signal processing, diagnostics and
communications. The RF module generates, transmits, receives and demodulates radar signals using two
Veoneer MMICs. Software algorithms calculate target parameters such as range, speed and angle and
this information is sent out to the vehicle over the CAN bus.
The components are assembled into a plastic housing that is laser welded together. The sensor has no
serviceable parts and can’t be opened without permanent damage.

6 Sensor Features
The BSD algorithm detects and reports “Objects of Interest" on either side of the vehicle, within a
specified “blind spot” zone. The feature generates a signal which is used to drive a visual display placed
in the outside view mirror to alert the driver to the presence of objects of interest within the defined
SBZA zone.
The LCA algorithm detects and reports to the driver that a 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 RCTA algorithm detects and reports “Objects of Interest” behind the host vehicle, withinaspecified
RCTA coverage zone. 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.
