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

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.

I. Introduction

This paper presents a highly integrated single-chip 77GHz FMCW radar, with built-in digital processing and 4TX-4RX mm-wave front-end, with emphasis on its high-performance radar processing and reconfigurability. The chip’s key high- performance hardware – for flexible waveform generation, high-throughput interference mitigation, FFT computation, data compression, and target detection, along with on-chip integration of front-end, DSP, MCUs, hardware security, and Ethernet interface – make this chip suitable for realizing state- of-the-art automotive radar systems and signal processing, such as what is summarized in [1].
