Abstract

This paper presents an interference-tolerant radar which can endure multiple signals transmitted from adjacent vehicles for autonomous driving applications. The interference-tolerant property has been realized by applying a specific code-division multiplexing method, involved with one-coincidence frequency hopping code, to the continuous-wave radar. We have implemented such a radar prototype in 65-nm CMOS operating at 24 GHz with 1 GHz bandwidth (equivalently with 15 cm range resolution). Measurements indicate that the prototype can support up to 22 adjacent vehicles simultaneously by using the optimal Hamming correlation property of the extended hyperbolic congruential code.
