Quickly Test Automotive mmWave Radar Chips

Solution Briefs

Introduction

 

Millimeter-wave (mmWave) radar is one of the essential radar sensors used in next-generation autonomous vehicles (AVs). In-vehicle sensors such as automotive radar and cameras in AVs generate a large amount of data. These data sets transmit through a high-speed digital interface to electronic control units to trigger the advanced driver assistance systems (ADAS) features. Automotive manufacturers must complete signal integrity and compliance testing of the mmWave radar and high-speed digital interfaces to ensure reliable system performance.

 

Use Case Summary

 

Millimeter-wave radar technology is evolving with wider modulation bandwidth, more complex modulation waveforms, higher modulation accuracy, more transceiver channels, and faster digital interface rates. The test instrument must combine the frequency domain analysis of multichannel mmWave signals with signal integrity and compliance analysis of high-speed digital interfaces. These capabilities are critical to meet the evolving requirements of millimeter-wave radar technology.

 

Solution Overview

 

These combined solutions can sample the 79 GHz radar signal with a sampling rate of 256 GSa/s and simultaneously create real-time acquisition tests for up to four channels. The Keysight Infiniium UXR-Series oscilloscope supports 10-bit ADC at 256 GSa/s, 5 GHz bandwidth, and analog signal path bandwidth up to 110 GHz. This automotive millimeter-wave radar chip test solution meets the requirements of multiple input, multiple output (MIMO) radar for interchannel amplitude and phase testing.
