Single-Chip 77GHz FMCW Automotive Radar with Integrated Front-End and Digital Processing

Abstract

This paper presents a single-chip automotive FMCW radar with integrated mm-wave and digital processing. The chip includes reconfigurable high-performance hardware for flexible waveform generation, interference mitigation, FFT, data compression, target detection and security acceleration, as well as a 76-81GHz FMCW transceiver, programmable 360MHz digital signal processor (DSP) and 300MHz microcontroller (MCU). This high-performance single-chip radar, realized in 45nm CMOS technology, is suitable for modern automotive corner radar applications.
