Safe - reliable - robust – very small design

Continental offers a new type of radar sensor, the ARS 308-21, as a possible adaptation in different application.

Measuring procedure

The rugged ARS 308-21 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 15 / sec.. A special feature of the device is the simultaneously measurement of great distances up to 200m, relative velocity and the angle relation between 2 objects.

Typical areas of application

  • Anti-collision protection for vehicles of every description (particul. autonomous)
  • Headway control also for far range (vehicles of every description, particularly autonomous)
  • Area monitoring system for far range, e.g. of hazardous or non-accessible areas
  • Traffic light approximation recognition, classification of objects (app. 90 single targets)
  • Object detection, e.g. in confusing or unclear areas
  • Unremarkable object detection by affix a protection cover before it

Advantages

  • Fast and safe: The ARS 308 dispels with the apparent contradiction between excellent great Measuring performance and a high degree of operational safety. The rugged ARS 308 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.
  • Reliable: The ARS 308 radar sensor is fail-safe and able to recognize troubles of the sensor and sensor environment and display it automatically.
  • Robust and very small design: By using a radar technology with less complex measuring principle and the development and mass production in automotive supply industry, the design › is kept very robust and small.
