摘要

The increasing amount of automotive radars makes mutual radar interference a prominent problem. Cooperation between the radars could not only minimize their mutual level of interference but would also enable remote radar nodes to operate synchronously for jointly improving their performance. The concept of Collaborative Time of Arrival (CToA) has recently been proposed for enabling distributed wireless network synchronization. In this paper, we explore the application of CToA to automotive radar systems for achieving sub-nanosecond level synchronization between radar nodes. The proposed scheme, dubbed “cooperative radar” (CoRD), opens a wide range of applications including bistatic automotive radars.
