Continental ARS 40821 Premium Long Range Radar Sensor 77 GHz

Safe - reliable - robust - smalldesign

the A.D.C. GmbH offers a new type of radar sensor, the ARS 408-21, as a possible adaptionindifferent Application and as premium version of the series40X.

Typical Areas ofapplication:

Anti-collision Protection for vehicles of every description (particul.Autonomous)

Headway Control also for far range (vehicles of every description, particularlyautonomous)

Area Monitoring system for far range, e.g. of hazardous or non-accessibleareas

Classification Ofobjects

Object Detection, e.g. in confusing or unclearareas

Unremarkable Object detection by affix a protection cover before it(radome)


the Rugged ARS 408-21 sensor from Continental measures independent the distance andve-locity(Doppler'sprinciple)toobjectswithoutreflectorinonemeasuringcycleduebasisof FMCW(FrequencyModulatedContinuousWave)withveryfastramps,witharealtimescan-ningof17/sec..Aspecialfeatureofthedeviceisthesimultaneouslymeasurementofgreat distancesup to 250 m, relative velocity and the Angle relation between 2objects.


Fast and safe:the ARS 408-21 dispels with the apparent contradiction betweenexcellentgreat Measuring performance and a high degree of operational safety. the rugged ARS408- 21 radar sensor is capable of Determining the distance to an object in real time scanningand dependent on the driving speed a Possible risk ofcollision.

Reliable:the ARS 408-21 radar sensor is fail-safe and able to recognize troubles ofthesensor and sensor environment and display itautomatically.

Robust and small Design:by Using a radar technology with less complex measuringprin- ciple and the development and mass production in Automotive supply industry, the designiskept very robust and small.
