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 a more complex system that also may include cameras, lidar, and other types 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
Typical Installation
The radar is typically installed in the positions of the vehicle depicted in Figure 1 often mounted behind a bumper or emblem.

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.

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, within a specified 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.
