MOre Safety for All by Radar Interference Mitigation (MOSARIM)

Since a number of years, millimeter-wave radar systems are being used for vehicular applications, predominantly in comfort function but increasingly in safety functions. Different frequencies and modulation schemes, emission powers, and radiation patterns are being used, but so far hardly any measures or precautions had been taken to reduce or avoid mutual interference. Within a few years the penetration rate of vehicular radar systems will have drastically increased and with it the risk for mutual interference. The goals of the MOSARIM project were:

  1. Assessment on actual radar interference potential with of-the-shelf radar sensors
  2. Generation of a starting platform based on common understandings and state-of-the-art
  3. Elaborate comprehensive and realistic simulation models regarding radar interference
  4. Specification and implementation of a norm radar interferer for automotive radar interference tests
  5. Find common applicable interference countermeasures to reduce mutual radar disturbance
  6. Generation of recommendations and guidelines for vehicular mutual radar interference mitigation

The KIT mainly worked on tasks 1-3.
