The number of vehicles on the road equipped with radars has been increasing for years and is estimated to reach 50% of cars by 2030. This rapid increase in radars will greatly increase the risk of harmful interference, especially since the radar waveform parameters are not heavily regulated within the 76-81 GHz band. Techniques for interference mitigation are thus becoming very important to ensure the correct operation of radars and upper-layer ADAS systems that depend on them in this complex environment. As presented in our previous study, by using a 4G, 5G or IEEE 802.11p/bd network, V2X technology can greatly help to mitigate interference by communicating radars physical properties and waveform parameters to surrounding vehicles. This data can be used to anticipate potential interferer and adapt FMCW radar parameters accordingly, but finding the perfect set of parameters can be difficult due to the lack of standardization of the bandwidth usage. To ease parameters selection, this article investigates the benefit of implementing a common channel access policy to split the bandwidth into orthogonal waveform and proposes a new strategy based on the radar orientation to mitigate interference.
