Automotive Radar - Chirp Analysis with R&S RTP Oscilloscope

August 09, 2021 by Rohde & Schwarz Download PDF

Application Note Overview

FMCW radar sensors are used in vehicles for adaptive cruise control and for blind-spot, lane-change, and cross traffic assistants. Radar sensors for the acquisition of the surroundings are key components for future vehicles with semi-autonomous and fully autonomous driving. Autonomous driving requires radars that reliably detect objects in the surrounding area. Radar makes it possible to quickly and precisely measure the radial velocity, range and azimuth and elevation angle of multiple objects. For this reason, the automobile industry is increasingly using this technology in advanced driver assistance systems (ADAS).

This application note focuses on how to measure and analyze FMCW radar signals with up to 6 GHz bandwidth with an R&S® RTP oscilloscope. On-board analysis features for pulse and chirp analysis for single- and multi-channel measurements are addressed, as well as the combination of oscilloscopes and R&S® VSE software. This resource also demonstrates the measurement of an FMCW radar signal in the 77 - 81GHz band with 4 GHz bandwidth.
