77GHz 250 meters Long Radar for Automotive Forward Collison Warning with ADAS and AEB functions.

 

When the vehicle is running in front of a sudden obstacle and other emergencies, the human response time is about 660 milliseconds, while the radar collision avoidance system response time is less than 50 milliseconds, radar is 13 times faster than people! Radar is an intelligent sensor to prevent vehicle from collision. System with radar technology can automatically detect obstacles and avoid collision of vehicles, pedestrians by alarming or braking, making the driving safety from "passive" to "active".

 

 

Radar features:

*Work in 77GHz-ISM-Band 

*Long range detection 250 meters 

*Accurately measure the direction, range, velocity and angle of stationary moving targets

*Protection class IP6k 9k

*Hige detection rate

Radar description:

The ARS 408 are 77 GHz long range radar sensors that have been specially designed by A.D.C. GmbH for deployment in automotive applications. Its purpose is the contactfree measurement of distance, speed and position by using digital formed beams with a F.o.V. (Field of View) of up to ±45° in near range for ARS
408 and up to ±9° in far range for ARS 408. The ARS 408 are typically mounted behind a secondary plastic surface (radome).

ARS408 77GHz Radar for Automotive Front Collision Warning and ADAS Accurate, Effective, Safe

 

 

The ARS 408 is a 77 GHz radar sensor with digital beam-forming scanning antenna which offers two independent scans for far and short range.
ARS 408 radar systems provides following features:
• Simultaneous detection of multiple stationary and moving objects with relative speed of

-400 to 200 km/h
• Determination of advanced object attributes like RCS, geometry and orientation (RCS = Radar Cross Section – value for reflectivity)
• Classification of moving objects as vehicle, motorbike, bicycle or pedestrian
• Dual scan provides detections in far range (up to 170 resp. 250 m) and extended field of view (FoV) in short range with high range resolution
• Configurable output of up to 250 raw detections (untracked clusters) or 100 tracked objects (tracks) via CAN bus
• Optional filtering and sorting of object list based on object attributes
• Collision warnings with up to eight regions of interest that can be defined via CAN bus
• Usage both on stationary and moving platform with optional input of sensor speed and yaw rate
• Scalable family approach with different control interface options
• Internal processing unit for additional software functionality on customer request
• Sensors designed to host sensor fusion (RAM, ROM, runtime) with other sensors (e.g. camera)
• Reduced cost and size to 3rd generation radar sensor ARS 30X
• Higher level of integration
• No moving parts
