6 Conclusion

Radar-radar interference is a stumbling block to the wide (and dense) deployment of radars. If it is not accounted for, it can lead to detection failures, ghost objects, and reduced radar range. Using different schemes, such as randomization, dithering, frequency planning, and localization and mitigation, it is possible to manage interference and provide robust performance.
