| description | The invention relates to a vehicle-mounted radar signal interference avoidance method and a V2X system. The method comprises the following steps: acquiring a channel matching request and a suggested channel value of a radar user; querying whether a target channel with the suggested channel value is idle, and if yes, allocating a channel according to a first preset value of the target channel; otherwise, finding the channel value closest to the suggested channel value in the channel set for distribution. Compared with the prior art, the method has the advantages that the requirement for the overlapping degree of control parameters such as time-frequency in a traditional scheme is broken through, the first preset value, namely the diversity of antenna polarization and the chirp slope, is introduced, the radar has channel resources with higher robustness, the radar is more suitable for a future large-bandwidth environment, and the performance of the radar is improved. And the limitation and constraint of time-fr |
