ARS 408


ARS 408-21 Long Range Radar (Far field radar sensor) 77 GHz. The ARS 408, is a premium adaption of the 40X Radar Sensors series.
  • Generally replacement of ARS 30X and 40X radar sensors
  • Simple but optimized anti-collision protection for vehicles of every description (particularly autonomous)
  • Headway control also for far field (vehicles of every description as cranes, construction machinery, fork lifts, tractors, harvester combines….particularly autonomous as AGV, special transporter, module transporter…)
  • Collision avoidance cranes of every description e.g. STS, RTG, RMG, overhead cranes, gantry cranes…
  • Area monitoring system for far field, e.g. of hazardous or non-accessible areas
  • Unremarkable object detection by affix a protection cover before it
  • Classification of objects (> 120 single cluster)
  • Object detection, e.g. in confusing or unclear areas
  • General distance and speed monitoring
  • Road traffic technology e.g. parking area surveillance
  • Rail traffic technology, approximation aid for bumper

Measuring procedure

The rugged ARS 408-21 sensor from Continental measures independent the distance and velocity (Doppler’s principle) to objects without reflector in one measuring cycle due basis of FMCW (Frequency Modulated Continuous Wave) with very fast ramps, with a real time scanning of 17 / sec.

A special feature of the device is the simultaneously measurement of great distances up to 250 m, relative velocity and the angle relation between 2 objects.

​A special software version supports a measurement range up to 1200m! (For objects with high RCS and a free field of view)

Features & Benefits

  • Fast and save: The ARS 408 dispels with the apparent contradiction between excellent great measuring performance and a high degree of operational safety. The optimized ARS 408-21 radar sensor is capable of determining the distance to an object in real time scanning and dependent on the driving speed a possible risk of collision.
  • Longer Range: The effective detection radius of the ARS 408 is up to 70 meters (about 76 yards) in the SR mode or up to 250 meters (about 273 yards) in the FR mode.
  • Reliable: The  ARS 408 radar sensor is fail-safe and able to recognize troubles of the sensor and sensor environment and display it automatically. Without use of filter it is possible to detect no ghost targets – every target is a real target.
  • All-weather capability: The ARS 408 is applicable at all weather conditions and has only low performance losses in extreme situations.
  • Cost-efficient: By using a radar technology with less complex measuring principle and the development and mass production in automotive supply industry, the costs are kept low.
  • Extended range possible: With a special software version, the ARS 408 is able to extend his measurement range up to 1,200 meters! (For objects with high RCS and a free field of view).


The device is fitted with one CAN bus interface as standard. Further interfaces can only be realized by using a converter. Software adaption, housing and / or hardware adaption are possible on demand and in case of assumption of costs or could be realized by the customer itself. The ARS 408 can be used for complex measuring tasks.
