Single-Chip Millimeter Wave Radar

摘要

This article describes the concept and development of a low cost, 77 GHz automotive radar system, including a single-chip CMOS millimeter wave transceiver. The architecture shown in Figure 8 will enable a consumer radar revolution as a result of advances in CMOS semiconductor processes and radar algorithms. The performance achieved from this radar matches standard radar theory, with the potential for further improvement in the information that can be extracted from a radar system. Our approach to this builds on Leb-edev's work on the information carrying capacity of a bosonic field.
